Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51744, here are decompositions:
- 23 + 51721 = 51744
- 31 + 51713 = 51744
- 53 + 51691 = 51744
- 61 + 51683 = 51744
- 71 + 51673 = 51744
- 97 + 51647 = 51744
- 107 + 51637 = 51744
- 113 + 51631 = 51744
Showing the first eight; more decompositions exist.
