Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646228, here are decompositions:

5 + 8646223 = 8646228
7 + 8646221 = 8646228
47 + 8646181 = 8646228
109 + 8646119 = 8646228
167 + 8646061 = 8646228
211 + 8646017 = 8646228
257 + 8645971 = 8646228
379 + 8645849 = 8646228

Showing the first eight; more decompositions exist.
