Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607882, here are decompositions:
- 13 + 31607869 = 31607882
- 43 + 31607839 = 31607882
- 193 + 31607689 = 31607882
- 199 + 31607683 = 31607882
- 211 + 31607671 = 31607882
- 283 + 31607599 = 31607882
- 331 + 31607551 = 31607882
- 379 + 31607503 = 31607882
Showing the first eight; more decompositions exist.
