Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644536, here are decompositions:

7 + 8644529 = 8644536
29 + 8644507 = 8644536
37 + 8644499 = 8644536
59 + 8644477 = 8644536
79 + 8644457 = 8644536
83 + 8644453 = 8644536
97 + 8644439 = 8644536
139 + 8644397 = 8644536

Showing the first eight; more decompositions exist.
