Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647456, here are decompositions:

47 + 8647409 = 8647456
89 + 8647367 = 8647456
107 + 8647349 = 8647456
179 + 8647277 = 8647456
227 + 8647229 = 8647456
263 + 8647193 = 8647456
317 + 8647139 = 8647456
449 + 8647007 = 8647456

Showing the first eight; more decompositions exist.
