Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647404, here are decompositions:

11 + 8647393 = 8647404
13 + 8647391 = 8647404
37 + 8647367 = 8647404
127 + 8647277 = 8647404
131 + 8647273 = 8647404
151 + 8647253 = 8647404
173 + 8647231 = 8647404
211 + 8647193 = 8647404

Showing the first eight; more decompositions exist.
