Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689732, here are decompositions:

3 + 8689729 = 8689732
5 + 8689727 = 8689732
59 + 8689673 = 8689732
71 + 8689661 = 8689732
83 + 8689649 = 8689732
89 + 8689643 = 8689732
179 + 8689553 = 8689732
239 + 8689493 = 8689732

Showing the first eight; more decompositions exist.
