Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 939720, here are decompositions:

7 + 939713 = 939720
13 + 939707 = 939720
43 + 939677 = 939720
59 + 939661 = 939720
71 + 939649 = 939720
97 + 939623 = 939720
107 + 939613 = 939720
109 + 939611 = 939720

Showing the first eight; more decompositions exist.
