Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947808, here are decompositions:

5 + 947803 = 947808
61 + 947747 = 947808
67 + 947741 = 947808
79 + 947729 = 947808
89 + 947719 = 947808
97 + 947711 = 947808
101 + 947707 = 947808
149 + 947659 = 947808

Showing the first eight; more decompositions exist.
