Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57512, here are decompositions:
- 19 + 57493 = 57512
- 139 + 57373 = 57512
- 163 + 57349 = 57512
- 181 + 57331 = 57512
- 211 + 57301 = 57512
- 229 + 57283 = 57512
- 241 + 57271 = 57512
- 271 + 57241 = 57512
Showing the first eight; more decompositions exist.
