Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939436, here are decompositions:

5 + 939431 = 939436
23 + 939413 = 939436
59 + 939377 = 939436
89 + 939347 = 939436
137 + 939299 = 939436
149 + 939287 = 939436
233 + 939203 = 939436
257 + 939179 = 939436

Showing the first eight; more decompositions exist.
