Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647136, here are decompositions:

7 + 8647129 = 8647136
13 + 8647123 = 8647136
73 + 8647063 = 8647136
109 + 8647027 = 8647136
193 + 8646943 = 8647136
283 + 8646853 = 8647136
313 + 8646823 = 8647136
577 + 8646559 = 8647136

Showing the first eight; more decompositions exist.
