Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526656, here are decompositions:
- 23 + 31526633 = 31526656
- 53 + 31526603 = 31526656
- 167 + 31526489 = 31526656
- 179 + 31526477 = 31526656
- 233 + 31526423 = 31526656
- 269 + 31526387 = 31526656
- 383 + 31526273 = 31526656
- 443 + 31526213 = 31526656
Showing the first eight; more decompositions exist.
