Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527632, here are decompositions:
- 109 + 31527523 = 31527632
- 151 + 31527481 = 31527632
- 379 + 31527253 = 31527632
- 421 + 31527211 = 31527632
- 439 + 31527193 = 31527632
- 523 + 31527109 = 31527632
- 691 + 31526941 = 31527632
- 733 + 31526899 = 31527632
Showing the first eight; more decompositions exist.
