Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689512, here are decompositions:

19 + 8689493 = 8689512
23 + 8689489 = 8689512
31 + 8689481 = 8689512
59 + 8689453 = 8689512
61 + 8689451 = 8689512
79 + 8689433 = 8689512
113 + 8689399 = 8689512
163 + 8689349 = 8689512

Showing the first eight; more decompositions exist.
