Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529268, here are decompositions:
- 11 + 31529257 = 31529268
- 19 + 31529249 = 31529268
- 101 + 31529167 = 31529268
- 179 + 31529089 = 31529268
- 181 + 31529087 = 31529268
- 271 + 31528997 = 31529268
- 359 + 31528909 = 31529268
- 457 + 31528811 = 31529268
Showing the first eight; more decompositions exist.
