Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51656, here are decompositions:
- 19 + 51637 = 51656
- 43 + 51613 = 51656
- 79 + 51577 = 51656
- 139 + 51517 = 51656
- 229 + 51427 = 51656
- 307 + 51349 = 51656
- 313 + 51343 = 51656
- 349 + 51307 = 51656
Showing the first eight; more decompositions exist.
