Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126748, here are decompositions:
- 5 + 126743 = 126748
- 29 + 126719 = 126748
- 107 + 126641 = 126748
- 137 + 126611 = 126748
- 197 + 126551 = 126748
- 257 + 126491 = 126748
- 389 + 126359 = 126748
- 431 + 126317 = 126748
Showing the first eight; more decompositions exist.
