Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639340, here are decompositions:

41 + 8639299 = 8639340
67 + 8639273 = 8639340
79 + 8639261 = 8639340
89 + 8639251 = 8639340
113 + 8639227 = 8639340
163 + 8639177 = 8639340
179 + 8639161 = 8639340
191 + 8639149 = 8639340

Showing the first eight; more decompositions exist.
