Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607652, here are decompositions:
- 23 + 31607629 = 31607652
- 53 + 31607599 = 31607652
- 71 + 31607581 = 31607652
- 73 + 31607579 = 31607652
- 101 + 31607551 = 31607652
- 149 + 31607503 = 31607652
- 163 + 31607489 = 31607652
- 179 + 31607473 = 31607652
Showing the first eight; more decompositions exist.
