Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526140, here are decompositions:
- 53 + 31526087 = 31526140
- 71 + 31526069 = 31526140
- 83 + 31526057 = 31526140
- 89 + 31526051 = 31526140
- 227 + 31525913 = 31526140
- 251 + 31525889 = 31526140
- 353 + 31525787 = 31526140
- 491 + 31525649 = 31526140
Showing the first eight; more decompositions exist.
