Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538942, here are decompositions:

3 + 538939 = 538942
11 + 538931 = 538942
71 + 538871 = 538942
101 + 538841 = 538942
113 + 538829 = 538942
179 + 538763 = 538942
191 + 538751 = 538942
233 + 538709 = 538942

Showing the first eight; more decompositions exist.
