Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526400, here are decompositions:
- 11 + 31526389 = 31526400
- 13 + 31526387 = 31526400
- 29 + 31526371 = 31526400
- 41 + 31526359 = 31526400
- 83 + 31526317 = 31526400
- 127 + 31526273 = 31526400
- 173 + 31526227 = 31526400
- 179 + 31526221 = 31526400
Showing the first eight; more decompositions exist.
