Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646550, here are decompositions:

47 + 8646503 = 8646550
53 + 8646497 = 8646550
71 + 8646479 = 8646550
149 + 8646401 = 8646550
173 + 8646377 = 8646550
233 + 8646317 = 8646550
251 + 8646299 = 8646550
257 + 8646293 = 8646550

Showing the first eight; more decompositions exist.
