Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645630, here are decompositions:

13 + 8645617 = 8645630
43 + 8645587 = 8645630
139 + 8645491 = 8645630
181 + 8645449 = 8645630
199 + 8645431 = 8645630
223 + 8645407 = 8645630
271 + 8645359 = 8645630
277 + 8645353 = 8645630

Showing the first eight; more decompositions exist.
