Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526658, here are decompositions:
- 11 + 31526647 = 31526658
- 41 + 31526617 = 31526658
- 131 + 31526527 = 31526658
- 181 + 31526477 = 31526658
- 227 + 31526431 = 31526658
- 239 + 31526419 = 31526658
- 269 + 31526389 = 31526658
- 271 + 31526387 = 31526658
Showing the first eight; more decompositions exist.
