Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641586, here are decompositions:

43 + 8641543 = 8641586
67 + 8641519 = 8641586
73 + 8641513 = 8641586
157 + 8641429 = 8641586
277 + 8641309 = 8641586
313 + 8641273 = 8641586
337 + 8641249 = 8641586
439 + 8641147 = 8641586

Showing the first eight; more decompositions exist.
