Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533552, here are decompositions:
- 5 + 31533547 = 31533552
- 19 + 31533533 = 31533552
- 41 + 31533511 = 31533552
- 53 + 31533499 = 31533552
- 101 + 31533451 = 31533552
- 103 + 31533449 = 31533552
- 139 + 31533413 = 31533552
- 163 + 31533389 = 31533552
Showing the first eight; more decompositions exist.
