Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659228, here are decompositions:

5 + 8659223 = 8659228
47 + 8659181 = 8659228
107 + 8659121 = 8659228
131 + 8659097 = 8659228
167 + 8659061 = 8659228
191 + 8659037 = 8659228
239 + 8658989 = 8659228
251 + 8658977 = 8659228

Showing the first eight; more decompositions exist.
