Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31453790, here are decompositions:
- 7 + 31453783 = 31453790
- 79 + 31453711 = 31453790
- 139 + 31453651 = 31453790
- 283 + 31453507 = 31453790
- 307 + 31453483 = 31453790
- 397 + 31453393 = 31453790
- 457 + 31453333 = 31453790
- 523 + 31453267 = 31453790
Showing the first eight; more decompositions exist.
