Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124978, here are decompositions:
- 59 + 124919 = 124978
- 71 + 124907 = 124978
- 131 + 124847 = 124978
- 179 + 124799 = 124978
- 197 + 124781 = 124978
- 239 + 124739 = 124978
- 257 + 124721 = 124978
- 401 + 124577 = 124978
Showing the first eight; more decompositions exist.
