Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526290, here are decompositions:
- 17 + 31526273 = 31526290
- 83 + 31526207 = 31526290
- 101 + 31526189 = 31526290
- 149 + 31526141 = 31526290
- 227 + 31526063 = 31526290
- 233 + 31526057 = 31526290
- 239 + 31526051 = 31526290
- 269 + 31526021 = 31526290
Showing the first eight; more decompositions exist.
