Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448126, here are decompositions:
- 103 + 31448023 = 31448126
- 109 + 31448017 = 31448126
- 139 + 31447987 = 31448126
- 163 + 31447963 = 31448126
- 223 + 31447903 = 31448126
- 313 + 31447813 = 31448126
- 499 + 31447627 = 31448126
- 733 + 31447393 = 31448126
Showing the first eight; more decompositions exist.
