Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126646, here are decompositions:
- 5 + 126641 = 126646
- 173 + 126473 = 126646
- 389 + 126257 = 126646
- 419 + 126227 = 126646
- 503 + 126143 = 126646
- 599 + 126047 = 126646
- 683 + 125963 = 126646
- 719 + 125927 = 126646
Showing the first eight; more decompositions exist.
