Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526160, here are decompositions:
- 19 + 31526141 = 31526160
- 73 + 31526087 = 31526160
- 97 + 31526063 = 31526160
- 103 + 31526057 = 31526160
- 109 + 31526051 = 31526160
- 139 + 31526021 = 31526160
- 179 + 31525981 = 31526160
- 233 + 31525927 = 31526160
Showing the first eight; more decompositions exist.
