Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939630, here are decompositions:

7 + 939623 = 939630
17 + 939613 = 939630
19 + 939611 = 939630
31 + 939599 = 939630
79 + 939551 = 939630
179 + 939451 = 939630
191 + 939439 = 939630
199 + 939431 = 939630

Showing the first eight; more decompositions exist.
