Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646486, here are decompositions:

7 + 8646479 = 8646486
29 + 8646457 = 8646486
83 + 8646403 = 8646486
97 + 8646389 = 8646486
109 + 8646377 = 8646486
157 + 8646329 = 8646486
193 + 8646293 = 8646486
227 + 8646259 = 8646486

Showing the first eight; more decompositions exist.
