Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947820, here are decompositions:

17 + 947803 = 947820
37 + 947783 = 947820
47 + 947773 = 947820
67 + 947753 = 947820
73 + 947747 = 947820
79 + 947741 = 947820
101 + 947719 = 947820
109 + 947711 = 947820

Showing the first eight; more decompositions exist.
