Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533560, here are decompositions:
- 13 + 31533547 = 31533560
- 43 + 31533517 = 31533560
- 61 + 31533499 = 31533560
- 109 + 31533451 = 31533560
- 151 + 31533409 = 31533560
- 181 + 31533379 = 31533560
- 433 + 31533127 = 31533560
- 463 + 31533097 = 31533560
Showing the first eight; more decompositions exist.
