Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938958, here are decompositions:

5 + 938953 = 938958
11 + 938947 = 938958
19 + 938939 = 938958
37 + 938921 = 938958
79 + 938879 = 938958
89 + 938869 = 938958
101 + 938857 = 938958
127 + 938831 = 938958

Showing the first eight; more decompositions exist.
