Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523712, here are decompositions:
- 5 + 31523707 = 31523712
- 43 + 31523669 = 31523712
- 53 + 31523659 = 31523712
- 61 + 31523651 = 31523712
- 79 + 31523633 = 31523712
- 113 + 31523599 = 31523712
- 173 + 31523539 = 31523712
- 191 + 31523521 = 31523712
Showing the first eight; more decompositions exist.
