Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647002, here are decompositions:

31 + 8646971 = 8647002
41 + 8646961 = 8647002
53 + 8646949 = 8647002
59 + 8646943 = 8647002
73 + 8646929 = 8647002
103 + 8646899 = 8647002
113 + 8646889 = 8647002
149 + 8646853 = 8647002

Showing the first eight; more decompositions exist.
