Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647454, here are decompositions:

7 + 8647447 = 8647454
37 + 8647417 = 8647454
43 + 8647411 = 8647454
61 + 8647393 = 8647454
181 + 8647273 = 8647454
223 + 8647231 = 8647454
271 + 8647183 = 8647454
331 + 8647123 = 8647454

Showing the first eight; more decompositions exist.
