Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529304, here are decompositions:
- 31 + 31529273 = 31529304
- 47 + 31529257 = 31529304
- 61 + 31529243 = 31529304
- 137 + 31529167 = 31529304
- 197 + 31529107 = 31529304
- 223 + 31529081 = 31529304
- 251 + 31529053 = 31529304
- 307 + 31528997 = 31529304
Showing the first eight; more decompositions exist.
