Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51668, here are decompositions:

31 + 51637 = 51668
37 + 51631 = 51668
61 + 51607 = 51668
151 + 51517 = 51668
157 + 51511 = 51668
181 + 51487 = 51668
229 + 51439 = 51668
241 + 51427 = 51668

Showing the first eight; more decompositions exist.
