Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939838, here are decompositions:

47 + 939791 = 939838
71 + 939767 = 939838
89 + 939749 = 939838
101 + 939737 = 939838
131 + 939707 = 939838
227 + 939611 = 939838
239 + 939599 = 939838
257 + 939581 = 939838

Showing the first eight; more decompositions exist.
