Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939636, here are decompositions:

13 + 939623 = 939636
23 + 939613 = 939636
37 + 939599 = 939636
149 + 939487 = 939636
167 + 939469 = 939636
193 + 939443 = 939636
197 + 939439 = 939636
223 + 939413 = 939636

Showing the first eight; more decompositions exist.
