Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636, here are decompositions:

7 + 8629 = 8636
13 + 8623 = 8636
37 + 8599 = 8636
73 + 8563 = 8636
97 + 8539 = 8636
109 + 8527 = 8636
193 + 8443 = 8636
283 + 8353 = 8636

Showing the first eight; more decompositions exist.
