Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471850, here are decompositions:
- 19 + 31471831 = 31471850
- 139 + 31471711 = 31471850
- 211 + 31471639 = 31471850
- 229 + 31471621 = 31471850
- 271 + 31471579 = 31471850
- 439 + 31471411 = 31471850
- 463 + 31471387 = 31471850
- 643 + 31471207 = 31471850
Showing the first eight; more decompositions exist.
