Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939018, here are decompositions:

7 + 939011 = 939018
11 + 939007 = 939018
29 + 938989 = 939018
37 + 938981 = 939018
71 + 938947 = 939018
79 + 938939 = 939018
97 + 938921 = 939018
137 + 938881 = 939018

Showing the first eight; more decompositions exist.
