Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947220, here are decompositions:

17 + 947203 = 947220
23 + 947197 = 947220
37 + 947183 = 947220
83 + 947137 = 947220
101 + 947119 = 947220
137 + 947083 = 947220
193 + 947027 = 947220
223 + 946997 = 947220

Showing the first eight; more decompositions exist.
