Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626648, here are decompositions:

5 + 8626643 = 8626648
71 + 8626577 = 8626648
131 + 8626517 = 8626648
179 + 8626469 = 8626648
227 + 8626421 = 8626648
257 + 8626391 = 8626648
347 + 8626301 = 8626648
419 + 8626229 = 8626648

Showing the first eight; more decompositions exist.
