Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626288, here are decompositions:

5 + 8626283 = 8626288
17 + 8626271 = 8626288
59 + 8626229 = 8626288
107 + 8626181 = 8626288
149 + 8626139 = 8626288
179 + 8626109 = 8626288
227 + 8626061 = 8626288
467 + 8625821 = 8626288

Showing the first eight; more decompositions exist.
