Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938090, here are decompositions:

7 + 938083 = 938090
19 + 938071 = 938090
31 + 938059 = 938090
37 + 938053 = 938090
67 + 938023 = 938090
73 + 938017 = 938090
163 + 937927 = 938090
199 + 937891 = 938090

Showing the first eight; more decompositions exist.
