Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533462, here are decompositions:
- 11 + 31533451 = 31533462
- 13 + 31533449 = 31533462
- 31 + 31533431 = 31533462
- 53 + 31533409 = 31533462
- 73 + 31533389 = 31533462
- 83 + 31533379 = 31533462
- 193 + 31533269 = 31533462
- 271 + 31533191 = 31533462
Showing the first eight; more decompositions exist.
