Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31513426, here are decompositions:
- 3 + 31513423 = 31513426
- 23 + 31513403 = 31513426
- 53 + 31513373 = 31513426
- 167 + 31513259 = 31513426
- 233 + 31513193 = 31513426
- 239 + 31513187 = 31513426
- 353 + 31513073 = 31513426
- 389 + 31513037 = 31513426
Showing the first eight; more decompositions exist.
