Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939278, here are decompositions:

31 + 939247 = 939278
97 + 939181 = 939278
157 + 939121 = 939278
271 + 939007 = 939278
331 + 938947 = 939278
397 + 938881 = 939278
409 + 938869 = 939278
421 + 938857 = 939278

Showing the first eight; more decompositions exist.
