Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529832, here are decompositions:
- 13 + 31529819 = 31529832
- 83 + 31529749 = 31529832
- 151 + 31529681 = 31529832
- 163 + 31529669 = 31529832
- 181 + 31529651 = 31529832
- 239 + 31529593 = 31529832
- 281 + 31529551 = 31529832
- 293 + 31529539 = 31529832
Showing the first eight; more decompositions exist.
