Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31457126, here are decompositions:
- 7 + 31457119 = 31457126
- 199 + 31456927 = 31457126
- 223 + 31456903 = 31457126
- 277 + 31456849 = 31457126
- 307 + 31456819 = 31457126
- 457 + 31456669 = 31457126
- 487 + 31456639 = 31457126
- 907 + 31456219 = 31457126
Showing the first eight; more decompositions exist.
