Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647408, here are decompositions:

17 + 8647391 = 8647408
41 + 8647367 = 8647408
59 + 8647349 = 8647408
131 + 8647277 = 8647408
179 + 8647229 = 8647408
227 + 8647181 = 8647408
251 + 8647157 = 8647408
269 + 8647139 = 8647408

Showing the first eight; more decompositions exist.
