Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939188, here are decompositions:

7 + 939181 = 939188
31 + 939157 = 939188
67 + 939121 = 939188
79 + 939109 = 939188
97 + 939091 = 939188
127 + 939061 = 939188
181 + 939007 = 939188
199 + 938989 = 939188

Showing the first eight; more decompositions exist.
