Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534656, here are decompositions:
- 5 + 31534651 = 31534656
- 19 + 31534637 = 31534656
- 59 + 31534597 = 31534656
- 67 + 31534589 = 31534656
- 103 + 31534553 = 31534656
- 113 + 31534543 = 31534656
- 163 + 31534493 = 31534656
- 173 + 31534483 = 31534656
Showing the first eight; more decompositions exist.
