Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522680, here are decompositions:
- 11 + 31522669 = 31522680
- 17 + 31522663 = 31522680
- 23 + 31522657 = 31522680
- 47 + 31522633 = 31522680
- 67 + 31522613 = 31522680
- 83 + 31522597 = 31522680
- 89 + 31522591 = 31522680
- 97 + 31522583 = 31522680
Showing the first eight; more decompositions exist.
