Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939658, here are decompositions:

47 + 939611 = 939658
59 + 939599 = 939658
107 + 939551 = 939658
227 + 939431 = 939658
281 + 939377 = 939658
311 + 939347 = 939658
359 + 939299 = 939658
479 + 939179 = 939658

Showing the first eight; more decompositions exist.
