Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538788, here are decompositions:

11 + 538777 = 538788
17 + 538771 = 538788
37 + 538751 = 538788
67 + 538721 = 538788
79 + 538709 = 538788
137 + 538651 = 538788
139 + 538649 = 538788
167 + 538621 = 538788

Showing the first eight; more decompositions exist.
