Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626720, here are decompositions:

23 + 8626697 = 8626720
29 + 8626691 = 8626720
107 + 8626613 = 8626720
191 + 8626529 = 8626720
227 + 8626493 = 8626720
233 + 8626487 = 8626720
251 + 8626469 = 8626720
419 + 8626301 = 8626720

Showing the first eight; more decompositions exist.
