Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526858, here are decompositions:
- 67 + 31526791 = 31526858
- 109 + 31526749 = 31526858
- 127 + 31526731 = 31526858
- 211 + 31526647 = 31526858
- 241 + 31526617 = 31526858
- 331 + 31526527 = 31526858
- 439 + 31526419 = 31526858
- 487 + 31526371 = 31526858
Showing the first eight; more decompositions exist.
