Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626788, here are decompositions:

11 + 8626777 = 8626788
41 + 8626747 = 8626788
89 + 8626699 = 8626788
97 + 8626691 = 8626788
167 + 8626621 = 8626788
211 + 8626577 = 8626788
239 + 8626549 = 8626788
271 + 8626517 = 8626788

Showing the first eight; more decompositions exist.
