Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529244, here are decompositions:
- 31 + 31529213 = 31529244
- 137 + 31529107 = 31529244
- 157 + 31529087 = 31529244
- 163 + 31529081 = 31529244
- 191 + 31529053 = 31529244
- 251 + 31528993 = 31529244
- 277 + 31528967 = 31529244
- 401 + 31528843 = 31529244
Showing the first eight; more decompositions exist.
