Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938938, here are decompositions:

17 + 938921 = 938938
59 + 938879 = 938938
107 + 938831 = 938938
131 + 938807 = 938938
191 + 938747 = 938938
257 + 938681 = 938938
347 + 938591 = 938938
401 + 938537 = 938938

Showing the first eight; more decompositions exist.
