Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529112, here are decompositions:
- 5 + 31529107 = 31529112
- 23 + 31529089 = 31529112
- 31 + 31529081 = 31529112
- 59 + 31529053 = 31529112
- 269 + 31528843 = 31529112
- 271 + 31528841 = 31529112
- 281 + 31528831 = 31529112
- 311 + 31528801 = 31529112
Showing the first eight; more decompositions exist.
