Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646556, here are decompositions:

53 + 8646503 = 8646556
59 + 8646497 = 8646556
167 + 8646389 = 8646556
179 + 8646377 = 8646556
227 + 8646329 = 8646556
239 + 8646317 = 8646556
257 + 8646299 = 8646556
263 + 8646293 = 8646556

Showing the first eight; more decompositions exist.
