Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529960, here are decompositions:
- 37 + 31529923 = 31529960
- 61 + 31529899 = 31529960
- 79 + 31529881 = 31529960
- 211 + 31529749 = 31529960
- 283 + 31529677 = 31529960
- 331 + 31529629 = 31529960
- 337 + 31529623 = 31529960
- 367 + 31529593 = 31529960
Showing the first eight; more decompositions exist.
