Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646438, here are decompositions:

37 + 8646401 = 8646438
61 + 8646377 = 8646438
109 + 8646329 = 8646438
139 + 8646299 = 8646438
179 + 8646259 = 8646438
181 + 8646257 = 8646438
191 + 8646247 = 8646438
211 + 8646227 = 8646438

Showing the first eight; more decompositions exist.
