Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639214, here are decompositions:

7 + 8639207 = 8639214
37 + 8639177 = 8639214
43 + 8639171 = 8639214
53 + 8639161 = 8639214
61 + 8639153 = 8639214
71 + 8639143 = 8639214
83 + 8639131 = 8639214
107 + 8639107 = 8639214

Showing the first eight; more decompositions exist.
