Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602220, here are decompositions:

7 + 8602213 = 8602220
19 + 8602201 = 8602220
43 + 8602177 = 8602220
181 + 8602039 = 8602220
223 + 8601997 = 8602220
229 + 8601991 = 8602220
241 + 8601979 = 8602220
283 + 8601937 = 8602220

Showing the first eight; more decompositions exist.
