Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647070, here are decompositions:

7 + 8647063 = 8647070
43 + 8647027 = 8647070
109 + 8646961 = 8647070
127 + 8646943 = 8647070
181 + 8646889 = 8647070
277 + 8646793 = 8647070
349 + 8646721 = 8647070
463 + 8646607 = 8647070

Showing the first eight; more decompositions exist.
