Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939690, here are decompositions:

13 + 939677 = 939690
29 + 939661 = 939690
41 + 939649 = 939690
67 + 939623 = 939690
79 + 939611 = 939690
109 + 939581 = 939690
139 + 939551 = 939690
179 + 939511 = 939690

Showing the first eight; more decompositions exist.
