Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8706228, here are decompositions:

7 + 8706221 = 8706228
31 + 8706197 = 8706228
59 + 8706169 = 8706228
79 + 8706149 = 8706228
127 + 8706101 = 8706228
149 + 8706079 = 8706228
227 + 8706001 = 8706228
229 + 8705999 = 8706228

Showing the first eight; more decompositions exist.
