Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627810, here are decompositions:

3 + 8627807 = 8627810
97 + 8627713 = 8627810
109 + 8627701 = 8627810
193 + 8627617 = 8627810
199 + 8627611 = 8627810
229 + 8627581 = 8627810
241 + 8627569 = 8627810
277 + 8627533 = 8627810

Showing the first eight; more decompositions exist.
