Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939020, here are decompositions:

13 + 939007 = 939020
31 + 938989 = 939020
37 + 938983 = 939020
67 + 938953 = 939020
73 + 938947 = 939020
139 + 938881 = 939020
151 + 938869 = 939020
163 + 938857 = 939020

Showing the first eight; more decompositions exist.
