Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 122866, here are decompositions:
- 5 + 122861 = 122866
- 17 + 122849 = 122866
- 47 + 122819 = 122866
- 89 + 122777 = 122866
- 113 + 122753 = 122866
- 173 + 122693 = 122866
- 257 + 122609 = 122866
- 269 + 122597 = 122866
Showing the first eight; more decompositions exist.
