Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537324, here are decompositions:
- 11 + 31537313 = 31537324
- 17 + 31537307 = 31537324
- 53 + 31537271 = 31537324
- 101 + 31537223 = 31537324
- 173 + 31537151 = 31537324
- 191 + 31537133 = 31537324
- 197 + 31537127 = 31537324
- 227 + 31537097 = 31537324
Showing the first eight; more decompositions exist.
