Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8602178, here are decompositions:

139 + 8602039 = 8602178
181 + 8601997 = 8602178
199 + 8601979 = 8602178
241 + 8601937 = 8602178
271 + 8601907 = 8602178
439 + 8601739 = 8602178
547 + 8601631 = 8602178
757 + 8601421 = 8602178

Showing the first eight; more decompositions exist.
