Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689872, here are decompositions:

19 + 8689853 = 8689872
29 + 8689843 = 8689872
31 + 8689841 = 8689872
73 + 8689799 = 8689872
199 + 8689673 = 8689872
211 + 8689661 = 8689872
223 + 8689649 = 8689872
229 + 8689643 = 8689872

Showing the first eight; more decompositions exist.
