Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8679228, here are decompositions:

7 + 8679221 = 8679228
11 + 8679217 = 8679228
29 + 8679199 = 8679228
149 + 8679079 = 8679228
157 + 8679071 = 8679228
191 + 8679037 = 8679228
277 + 8678951 = 8679228
281 + 8678947 = 8679228

Showing the first eight; more decompositions exist.
