Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645610, here are decompositions:

13 + 8645597 = 8645610
23 + 8645587 = 8645610
31 + 8645579 = 8645610
67 + 8645543 = 8645610
167 + 8645443 = 8645610
179 + 8645431 = 8645610
229 + 8645381 = 8645610
251 + 8645359 = 8645610

Showing the first eight; more decompositions exist.
