Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939804, here are decompositions:

11 + 939793 = 939804
13 + 939791 = 939804
31 + 939773 = 939804
37 + 939767 = 939804
67 + 939737 = 939804
97 + 939707 = 939804
127 + 939677 = 939804
181 + 939623 = 939804

Showing the first eight; more decompositions exist.
