Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122918, here are decompositions:
- 31 + 122887 = 122918
- 79 + 122839 = 122918
- 157 + 122761 = 122918
- 199 + 122719 = 122918
- 307 + 122611 = 122918
- 409 + 122509 = 122918
- 421 + 122497 = 122918
- 571 + 122347 = 122918
Showing the first eight; more decompositions exist.
