Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647008, here are decompositions:

37 + 8646971 = 8647008
47 + 8646961 = 8647008
59 + 8646949 = 8647008
61 + 8646947 = 8647008
79 + 8646929 = 8647008
109 + 8646899 = 8647008
157 + 8646851 = 8647008
191 + 8646817 = 8647008

Showing the first eight; more decompositions exist.
