Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538908, here are decompositions:

31 + 538877 = 538908
37 + 538871 = 538908
67 + 538841 = 538908
79 + 538829 = 538908
107 + 538801 = 538908
109 + 538799 = 538908
131 + 538777 = 538908
137 + 538771 = 538908

Showing the first eight; more decompositions exist.
