Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639330, here are decompositions:

31 + 8639299 = 8639330
67 + 8639263 = 8639330
79 + 8639251 = 8639330
103 + 8639227 = 8639330
181 + 8639149 = 8639330
199 + 8639131 = 8639330
211 + 8639119 = 8639330
223 + 8639107 = 8639330

Showing the first eight; more decompositions exist.
