Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644036, here are decompositions:

17 + 8644019 = 8644036
83 + 8643953 = 8644036
113 + 8643923 = 8644036
197 + 8643839 = 8644036
239 + 8643797 = 8644036
257 + 8643779 = 8644036
389 + 8643647 = 8644036
449 + 8643587 = 8644036

Showing the first eight; more decompositions exist.
