Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471406, here are decompositions:
- 19 + 31471387 = 31471406
- 193 + 31471213 = 31471406
- 199 + 31471207 = 31471406
- 283 + 31471123 = 31471406
- 313 + 31471093 = 31471406
- 409 + 31470997 = 31471406
- 607 + 31470799 = 31471406
- 613 + 31470793 = 31471406
Showing the first eight; more decompositions exist.
