Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125078, here are decompositions:
- 61 + 125017 = 125078
- 97 + 124981 = 125078
- 127 + 124951 = 125078
- 181 + 124897 = 125078
- 307 + 124771 = 125078
- 379 + 124699 = 125078
- 409 + 124669 = 125078
- 601 + 124477 = 125078
Showing the first eight; more decompositions exist.
