Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529762, here are decompositions:
- 13 + 31529749 = 31529762
- 139 + 31529623 = 31529762
- 211 + 31529551 = 31529762
- 223 + 31529539 = 31529762
- 241 + 31529521 = 31529762
- 283 + 31529479 = 31529762
- 331 + 31529431 = 31529762
- 349 + 31529413 = 31529762
Showing the first eight; more decompositions exist.
