Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752686, here are decompositions:

29 + 8752657 = 8752686
43 + 8752643 = 8752686
67 + 8752619 = 8752686
73 + 8752613 = 8752686
113 + 8752573 = 8752686
149 + 8752537 = 8752686
179 + 8752507 = 8752686
269 + 8752417 = 8752686

Showing the first eight; more decompositions exist.
