Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639174, here are decompositions:

3 + 8639171 = 8639174
13 + 8639161 = 8639174
31 + 8639143 = 8639174
43 + 8639131 = 8639174
67 + 8639107 = 8639174
163 + 8639011 = 8639174
223 + 8638951 = 8639174
241 + 8638933 = 8639174

Showing the first eight; more decompositions exist.
