Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647540, here are decompositions:

3 + 8647537 = 8647540
29 + 8647511 = 8647540
71 + 8647469 = 8647540
131 + 8647409 = 8647540
149 + 8647391 = 8647540
173 + 8647367 = 8647540
191 + 8647349 = 8647540
263 + 8647277 = 8647540

Showing the first eight; more decompositions exist.
