Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644732, here are decompositions:

3 + 8644729 = 8644732
29 + 8644703 = 8644732
53 + 8644679 = 8644732
71 + 8644661 = 8644732
179 + 8644553 = 8644732
233 + 8644499 = 8644732
281 + 8644451 = 8644732
293 + 8644439 = 8644732

Showing the first eight; more decompositions exist.
