Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689474, here are decompositions:

11 + 8689463 = 8689474
23 + 8689451 = 8689474
41 + 8689433 = 8689474
173 + 8689301 = 8689474
191 + 8689283 = 8689474
251 + 8689223 = 8689474
257 + 8689217 = 8689474
293 + 8689181 = 8689474

Showing the first eight; more decompositions exist.
