Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647466, here are decompositions:

7 + 8647459 = 8647466
19 + 8647447 = 8647466
73 + 8647393 = 8647466
97 + 8647369 = 8647466
193 + 8647273 = 8647466
283 + 8647183 = 8647466
337 + 8647129 = 8647466
439 + 8647027 = 8647466

Showing the first eight; more decompositions exist.
