Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526238, here are decompositions:
- 11 + 31526227 = 31526238
- 17 + 31526221 = 31526238
- 31 + 31526207 = 31526238
- 41 + 31526197 = 31526238
- 47 + 31526191 = 31526238
- 97 + 31526141 = 31526238
- 151 + 31526087 = 31526238
- 181 + 31526057 = 31526238
Showing the first eight; more decompositions exist.
