Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512850, here are decompositions:
- 11 + 31512839 = 31512850
- 23 + 31512827 = 31512850
- 71 + 31512779 = 31512850
- 167 + 31512683 = 31512850
- 233 + 31512617 = 31512850
- 263 + 31512587 = 31512850
- 293 + 31512557 = 31512850
- 491 + 31512359 = 31512850
Showing the first eight; more decompositions exist.
