Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529264, here are decompositions:
- 7 + 31529257 = 31529264
- 97 + 31529167 = 31529264
- 157 + 31529107 = 31529264
- 211 + 31529053 = 31529264
- 271 + 31528993 = 31529264
- 421 + 31528843 = 31529264
- 433 + 31528831 = 31529264
- 457 + 31528807 = 31529264
Showing the first eight; more decompositions exist.
