Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611744, here are decompositions:
- 7 + 31611737 = 31611744
- 11 + 31611733 = 31611744
- 41 + 31611703 = 31611744
- 71 + 31611673 = 31611744
- 97 + 31611647 = 31611744
- 103 + 31611641 = 31611744
- 127 + 31611617 = 31611744
- 137 + 31611607 = 31611744
Showing the first eight; more decompositions exist.
