Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51638, here are decompositions:

7 + 51631 = 51638
31 + 51607 = 51638
61 + 51577 = 51638
127 + 51511 = 51638
151 + 51487 = 51638
157 + 51481 = 51638
199 + 51439 = 51638
211 + 51427 = 51638

Showing the first eight; more decompositions exist.
