Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939450, here are decompositions:

7 + 939443 = 939450
11 + 939439 = 939450
19 + 939431 = 939450
37 + 939413 = 939450
59 + 939391 = 939450
73 + 939377 = 939450
89 + 939361 = 939450
101 + 939349 = 939450

Showing the first eight; more decompositions exist.
