Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529328, here are decompositions:
- 7 + 31529321 = 31529328
- 59 + 31529269 = 31529328
- 71 + 31529257 = 31529328
- 79 + 31529249 = 31529328
- 109 + 31529219 = 31529328
- 179 + 31529149 = 31529328
- 239 + 31529089 = 31529328
- 241 + 31529087 = 31529328
Showing the first eight; more decompositions exist.
