Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939684, here are decompositions:

7 + 939677 = 939684
23 + 939661 = 939684
61 + 939623 = 939684
71 + 939613 = 939684
73 + 939611 = 939684
103 + 939581 = 939684
173 + 939511 = 939684
197 + 939487 = 939684

Showing the first eight; more decompositions exist.
