Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537576, here are decompositions:
- 3 + 31537573 = 31537576
- 17 + 31537559 = 31537576
- 29 + 31537547 = 31537576
- 107 + 31537469 = 31537576
- 167 + 31537409 = 31537576
- 263 + 31537313 = 31537576
- 269 + 31537307 = 31537576
- 347 + 31537229 = 31537576
Showing the first eight; more decompositions exist.
