Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947784, here are decompositions:

11 + 947773 = 947784
31 + 947753 = 947784
37 + 947747 = 947784
41 + 947743 = 947784
43 + 947741 = 947784
73 + 947711 = 947784
137 + 947647 = 947784
157 + 947627 = 947784

Showing the first eight; more decompositions exist.
