Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1000938, here are decompositions:

7 + 1000931 = 1000938
17 + 1000921 = 1000938
19 + 1000919 = 1000938
31 + 1000907 = 1000938
79 + 1000859 = 1000938
89 + 1000849 = 1000938
109 + 1000829 = 1000938
241 + 1000697 = 1000938

Showing the first eight; more decompositions exist.
