Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689572, here are decompositions:

19 + 8689553 = 8689572
29 + 8689543 = 8689572
43 + 8689529 = 8689572
79 + 8689493 = 8689572
83 + 8689489 = 8689572
109 + 8689463 = 8689572
139 + 8689433 = 8689572
173 + 8689399 = 8689572

Showing the first eight; more decompositions exist.
