Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529594, here are decompositions:
- 37 + 31529557 = 31529594
- 43 + 31529551 = 31529594
- 73 + 31529521 = 31529594
- 163 + 31529431 = 31529594
- 181 + 31529413 = 31529594
- 241 + 31529353 = 31529594
- 337 + 31529257 = 31529594
- 487 + 31529107 = 31529594
Showing the first eight; more decompositions exist.
