Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947790, here are decompositions:

7 + 947783 = 947790
17 + 947773 = 947790
37 + 947753 = 947790
43 + 947747 = 947790
47 + 947743 = 947790
61 + 947729 = 947790
71 + 947719 = 947790
79 + 947711 = 947790

Showing the first eight; more decompositions exist.
