Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51788, here are decompositions:

19 + 51769 = 51788
67 + 51721 = 51788
97 + 51691 = 51788
109 + 51679 = 51788
151 + 51637 = 51788
157 + 51631 = 51788
181 + 51607 = 51788
211 + 51577 = 51788

Showing the first eight; more decompositions exist.
