Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947778, here are decompositions:

5 + 947773 = 947778
31 + 947747 = 947778
37 + 947741 = 947778
59 + 947719 = 947778
67 + 947711 = 947778
71 + 947707 = 947778
127 + 947651 = 947778
131 + 947647 = 947778

Showing the first eight; more decompositions exist.
