Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125698, here are decompositions:
- 5 + 125693 = 125698
- 11 + 125687 = 125698
- 29 + 125669 = 125698
- 47 + 125651 = 125698
- 59 + 125639 = 125698
- 71 + 125627 = 125698
- 101 + 125597 = 125698
- 107 + 125591 = 125698
Showing the first eight; more decompositions exist.
