Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526080, here are decompositions:
- 11 + 31526069 = 31526080
- 17 + 31526063 = 31526080
- 23 + 31526057 = 31526080
- 29 + 31526051 = 31526080
- 59 + 31526021 = 31526080
- 167 + 31525913 = 31526080
- 191 + 31525889 = 31526080
- 239 + 31525841 = 31526080
Showing the first eight; more decompositions exist.
