Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646450, here are decompositions:

47 + 8646403 = 8646450
61 + 8646389 = 8646450
73 + 8646377 = 8646450
89 + 8646361 = 8646450
151 + 8646299 = 8646450
157 + 8646293 = 8646450
173 + 8646277 = 8646450
181 + 8646269 = 8646450

Showing the first eight; more decompositions exist.
