Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631686, here are decompositions:

13 + 8631673 = 8631686
307 + 8631379 = 8631686
313 + 8631373 = 8631686
367 + 8631319 = 8631686
379 + 8631307 = 8631686
409 + 8631277 = 8631686
439 + 8631247 = 8631686
457 + 8631229 = 8631686

Showing the first eight; more decompositions exist.
