Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8607228, here are decompositions:

5 + 8607223 = 8607228
11 + 8607217 = 8607228
31 + 8607197 = 8607228
37 + 8607191 = 8607228
61 + 8607167 = 8607228
89 + 8607139 = 8607228
151 + 8607077 = 8607228
167 + 8607061 = 8607228

Showing the first eight; more decompositions exist.
