Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537188, here are decompositions:
- 37 + 31537151 = 31537188
- 41 + 31537147 = 31537188
- 61 + 31537127 = 31537188
- 101 + 31537087 = 31537188
- 139 + 31537049 = 31537188
- 149 + 31537039 = 31537188
- 197 + 31536991 = 31537188
- 229 + 31536959 = 31537188
Showing the first eight; more decompositions exist.
