Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645636, here are decompositions:

3 + 8645633 = 8645636
19 + 8645617 = 8645636
193 + 8645443 = 8645636
229 + 8645407 = 8645636
277 + 8645359 = 8645636
283 + 8645353 = 8645636
367 + 8645269 = 8645636
379 + 8645257 = 8645636

Showing the first eight; more decompositions exist.
