Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939478, here are decompositions:

47 + 939431 = 939478
101 + 939377 = 939478
131 + 939347 = 939478
179 + 939299 = 939478
191 + 939287 = 939478
311 + 939167 = 939478
359 + 939119 = 939478
389 + 939089 = 939478

Showing the first eight; more decompositions exist.
