Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31596840, here are decompositions:
- 19 + 31596821 = 31596840
- 43 + 31596797 = 31596840
- 47 + 31596793 = 31596840
- 71 + 31596769 = 31596840
- 83 + 31596757 = 31596840
- 89 + 31596751 = 31596840
- 97 + 31596743 = 31596840
- 127 + 31596713 = 31596840
Showing the first eight; more decompositions exist.
