Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647012, here are decompositions:

5 + 8647007 = 8647012
41 + 8646971 = 8647012
83 + 8646929 = 8647012
113 + 8646899 = 8647012
191 + 8646821 = 8647012
233 + 8646779 = 8647012
293 + 8646719 = 8647012
431 + 8646581 = 8647012

Showing the first eight; more decompositions exist.
