Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538938, here are decompositions:

7 + 538931 = 538938
11 + 538927 = 538938
17 + 538921 = 538938
61 + 538877 = 538938
67 + 538871 = 538938
97 + 538841 = 538938
109 + 538829 = 538938
137 + 538801 = 538938

Showing the first eight; more decompositions exist.
