Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529988, here are decompositions:
- 11 + 31529977 = 31529988
- 19 + 31529969 = 31529988
- 89 + 31529899 = 31529988
- 97 + 31529891 = 31529988
- 107 + 31529881 = 31529988
- 239 + 31529749 = 31529988
- 271 + 31529717 = 31529988
- 307 + 31529681 = 31529988
Showing the first eight; more decompositions exist.
