Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947156, here are decompositions:

19 + 947137 = 947156
37 + 947119 = 947156
73 + 947083 = 947156
163 + 946993 = 947156
283 + 946873 = 947156
337 + 946819 = 947156
373 + 946783 = 947156
439 + 946717 = 947156

Showing the first eight; more decompositions exist.
