Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687474, here are decompositions:

7 + 8687467 = 8687474
13 + 8687461 = 8687474
73 + 8687401 = 8687474
157 + 8687317 = 8687474
241 + 8687233 = 8687474
277 + 8687197 = 8687474
787 + 8686687 = 8687474
823 + 8686651 = 8687474

Showing the first eight; more decompositions exist.
