Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526190, here are decompositions:
- 103 + 31526087 = 31526190
- 107 + 31526083 = 31526190
- 127 + 31526063 = 31526190
- 139 + 31526051 = 31526190
- 233 + 31525957 = 31526190
- 239 + 31525951 = 31526190
- 263 + 31525927 = 31526190
- 271 + 31525919 = 31526190
Showing the first eight; more decompositions exist.
