Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529260, here are decompositions:
- 3 + 31529257 = 31529260
- 11 + 31529249 = 31529260
- 17 + 31529243 = 31529260
- 41 + 31529219 = 31529260
- 47 + 31529213 = 31529260
- 173 + 31529087 = 31529260
- 179 + 31529081 = 31529260
- 263 + 31528997 = 31529260
Showing the first eight; more decompositions exist.
