Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529696, here are decompositions:
- 19 + 31529677 = 31529696
- 67 + 31529629 = 31529696
- 73 + 31529623 = 31529696
- 103 + 31529593 = 31529696
- 139 + 31529557 = 31529696
- 157 + 31529539 = 31529696
- 283 + 31529413 = 31529696
- 337 + 31529359 = 31529696
Showing the first eight; more decompositions exist.
