Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526158, here are decompositions:
- 17 + 31526141 = 31526158
- 71 + 31526087 = 31526158
- 89 + 31526069 = 31526158
- 101 + 31526057 = 31526158
- 107 + 31526051 = 31526158
- 137 + 31526021 = 31526158
- 239 + 31525919 = 31526158
- 269 + 31525889 = 31526158
Showing the first eight; more decompositions exist.
