[Intro] （管弦乐演奏） [Verse] In the realm of numbers, where logic prevails A function emerges, defining the primes It checks the small numbers, the basics we know And eliminates the frauds, as it starts to grow [Chorus] Isprime.symphony, the tune of the truth Dividing and checking, in pursuit of proof Through crashes and harmony, the answer revealed The essence of numbers, the prime concealed [Verse 2] Beneath the surface, where patterns reside It skips the evens, and divides by three Assuming prime, until it's proven false It's on a quest to validate, the numbers we hold [Bridge] From five and beyond, it's on a journey Checking every second number, in its own parity A melody of logic, a prime detection In the end, the truth's reflection [Chorus] Isprime.symphony, the numbers align Revealing the primes, through the orchestral design The cycle continues, the checks never end In the symphony of numbers, the primes transcend [Outro] In the grandeur of the symphony, the truth we find The beauty of the primes, in every note and mind [Ending] （管弦乐高潮）
