Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939238, here are decompositions:

59 + 939179 = 939238
71 + 939167 = 939238
149 + 939089 = 939238
227 + 939011 = 939238
257 + 938981 = 939238
269 + 938969 = 939238
317 + 938921 = 939238
359 + 938879 = 939238

Showing the first eight; more decompositions exist.
