Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538782, here are decompositions:

5 + 538777 = 538782
11 + 538771 = 538782
19 + 538763 = 538782
31 + 538751 = 538782
43 + 538739 = 538782
59 + 538723 = 538782
61 + 538721 = 538782
71 + 538711 = 538782

Showing the first eight; more decompositions exist.
