Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530048, here are decompositions:
- 5 + 31530043 = 31530048
- 19 + 31530029 = 31530048
- 31 + 31530017 = 31530048
- 47 + 31530001 = 31530048
- 71 + 31529977 = 31530048
- 79 + 31529969 = 31530048
- 149 + 31529899 = 31530048
- 157 + 31529891 = 31530048
Showing the first eight; more decompositions exist.
