Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647422, here are decompositions:

5 + 8647417 = 8647422
11 + 8647411 = 8647422
13 + 8647409 = 8647422
29 + 8647393 = 8647422
31 + 8647391 = 8647422
53 + 8647369 = 8647422
73 + 8647349 = 8647422
149 + 8647273 = 8647422

Showing the first eight; more decompositions exist.
