Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529814, here are decompositions:
- 31 + 31529783 = 31529814
- 97 + 31529717 = 31529814
- 137 + 31529677 = 31529814
- 163 + 31529651 = 31529814
- 191 + 31529623 = 31529814
- 257 + 31529557 = 31529814
- 263 + 31529551 = 31529814
- 293 + 31529521 = 31529814
Showing the first eight; more decompositions exist.
