Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639262, here are decompositions:

11 + 8639251 = 8639262
13 + 8639249 = 8639262
43 + 8639219 = 8639262
101 + 8639161 = 8639262
109 + 8639153 = 8639262
113 + 8639149 = 8639262
131 + 8639131 = 8639262
139 + 8639123 = 8639262

Showing the first eight; more decompositions exist.
