Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939618, here are decompositions:

5 + 939613 = 939618
7 + 939611 = 939618
19 + 939599 = 939618
37 + 939581 = 939618
67 + 939551 = 939618
107 + 939511 = 939618
131 + 939487 = 939618
149 + 939469 = 939618

Showing the first eight; more decompositions exist.
