Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938916, here are decompositions:

37 + 938879 = 938916
47 + 938869 = 938916
59 + 938857 = 938916
73 + 938843 = 938916
89 + 938827 = 938916
109 + 938807 = 938916
113 + 938803 = 938916
239 + 938677 = 938916

Showing the first eight; more decompositions exist.
