Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537268, here are decompositions:
- 67 + 31537201 = 31537268
- 181 + 31537087 = 31537268
- 229 + 31537039 = 31537268
- 241 + 31537027 = 31537268
- 277 + 31536991 = 31537268
- 331 + 31536937 = 31537268
- 397 + 31536871 = 31537268
- 421 + 31536847 = 31537268
Showing the first eight; more decompositions exist.
