Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634636, here are decompositions:

7 + 8634629 = 8634636
19 + 8634617 = 8634636
79 + 8634557 = 8634636
97 + 8634539 = 8634636
139 + 8634497 = 8634636
167 + 8634469 = 8634636
223 + 8634413 = 8634636
239 + 8634397 = 8634636

Showing the first eight; more decompositions exist.
