Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538822, here are decompositions:

5 + 538817 = 538822
23 + 538799 = 538822
59 + 538763 = 538822
71 + 538751 = 538822
83 + 538739 = 538822
101 + 538721 = 538822
113 + 538709 = 538822
173 + 538649 = 538822

Showing the first eight; more decompositions exist.
