Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125628, here are decompositions:
- 7 + 125621 = 125628
- 11 + 125617 = 125628
- 31 + 125597 = 125628
- 37 + 125591 = 125628
- 89 + 125539 = 125628
- 101 + 125527 = 125628
- 131 + 125497 = 125628
- 157 + 125471 = 125628
Showing the first eight; more decompositions exist.
