Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939218, here are decompositions:

37 + 939181 = 939218
61 + 939157 = 939218
97 + 939121 = 939218
109 + 939109 = 939218
127 + 939091 = 939218
157 + 939061 = 939218
199 + 939019 = 939218
211 + 939007 = 939218

Showing the first eight; more decompositions exist.
