Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939158, here are decompositions:

37 + 939121 = 939158
67 + 939091 = 939158
97 + 939061 = 939158
139 + 939019 = 939158
151 + 939007 = 939158
211 + 938947 = 939158
277 + 938881 = 939158
331 + 938827 = 939158

Showing the first eight; more decompositions exist.
