Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522736, here are decompositions:
- 19 + 31522717 = 31522736
- 43 + 31522693 = 31522736
- 67 + 31522669 = 31522736
- 73 + 31522663 = 31522736
- 79 + 31522657 = 31522736
- 103 + 31522633 = 31522736
- 139 + 31522597 = 31522736
- 277 + 31522459 = 31522736
Showing the first eight; more decompositions exist.
