Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639290, here are decompositions:

17 + 8639273 = 8639290
29 + 8639261 = 8639290
41 + 8639249 = 8639290
71 + 8639219 = 8639290
83 + 8639207 = 8639290
113 + 8639177 = 8639290
137 + 8639153 = 8639290
167 + 8639123 = 8639290

Showing the first eight; more decompositions exist.
