Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939650, here are decompositions:

37 + 939613 = 939650
139 + 939511 = 939650
163 + 939487 = 939650
181 + 939469 = 939650
199 + 939451 = 939650
211 + 939439 = 939650
277 + 939373 = 939650
421 + 939229 = 939650

Showing the first eight; more decompositions exist.
