Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 115644, here are decompositions:
- 7 + 115637 = 115644
- 13 + 115631 = 115644
- 31 + 115613 = 115644
- 41 + 115603 = 115644
- 43 + 115601 = 115644
- 47 + 115597 = 115644
- 73 + 115571 = 115644
- 83 + 115561 = 115644
Showing the first eight; more decompositions exist.
