Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526170, here are decompositions:
- 29 + 31526141 = 31526170
- 83 + 31526087 = 31526170
- 101 + 31526069 = 31526170
- 107 + 31526063 = 31526170
- 113 + 31526057 = 31526170
- 149 + 31526021 = 31526170
- 251 + 31525919 = 31526170
- 257 + 31525913 = 31526170
Showing the first eight; more decompositions exist.
