Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938940, here are decompositions:

19 + 938921 = 938940
59 + 938881 = 938940
61 + 938879 = 938940
71 + 938869 = 938940
83 + 938857 = 938940
97 + 938843 = 938940
109 + 938831 = 938940
113 + 938827 = 938940

Showing the first eight; more decompositions exist.
