Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 938120, here are decompositions:

3 + 938117 = 938120
13 + 938107 = 938120
31 + 938089 = 938120
37 + 938083 = 938120
61 + 938059 = 938120
67 + 938053 = 938120
97 + 938023 = 938120
103 + 938017 = 938120

Showing the first eight; more decompositions exist.
