Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947146, here are decompositions:

17 + 947129 = 947146
113 + 947033 = 947146
149 + 946997 = 947146
197 + 946949 = 947146
227 + 946919 = 947146
269 + 946877 = 947146
293 + 946853 = 947146
419 + 946727 = 947146

Showing the first eight; more decompositions exist.
