Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8613228, here are decompositions:

7 + 8613221 = 8613228
17 + 8613211 = 8613228
47 + 8613181 = 8613228
67 + 8613161 = 8613228
79 + 8613149 = 8613228
101 + 8613127 = 8613228
137 + 8613091 = 8613228
139 + 8613089 = 8613228

Showing the first eight; more decompositions exist.
