Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939128, here are decompositions:

7 + 939121 = 939128
19 + 939109 = 939128
37 + 939091 = 939128
67 + 939061 = 939128
109 + 939019 = 939128
139 + 938989 = 939128
181 + 938947 = 939128
271 + 938857 = 939128

Showing the first eight; more decompositions exist.
