Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646474, here are decompositions:

17 + 8646457 = 8646474
71 + 8646403 = 8646474
73 + 8646401 = 8646474
97 + 8646377 = 8646474
113 + 8646361 = 8646474
157 + 8646317 = 8646474
181 + 8646293 = 8646474
197 + 8646277 = 8646474

Showing the first eight; more decompositions exist.
