Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641550, here are decompositions:

3 + 8641547 = 8641550
7 + 8641543 = 8641550
31 + 8641519 = 8641550
37 + 8641513 = 8641550
79 + 8641471 = 8641550
97 + 8641453 = 8641550
199 + 8641351 = 8641550
223 + 8641327 = 8641550

Showing the first eight; more decompositions exist.
