Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647124, here are decompositions:

61 + 8647063 = 8647124
97 + 8647027 = 8647124
103 + 8647021 = 8647124
163 + 8646961 = 8647124
181 + 8646943 = 8647124
271 + 8646853 = 8647124
307 + 8646817 = 8647124
331 + 8646793 = 8647124

Showing the first eight; more decompositions exist.
