Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939220, here are decompositions:

17 + 939203 = 939220
41 + 939179 = 939220
53 + 939167 = 939220
101 + 939119 = 939220
131 + 939089 = 939220
239 + 938981 = 939220
251 + 938969 = 939220
257 + 938963 = 939220

Showing the first eight; more decompositions exist.
