Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752666, here are decompositions:

23 + 8752643 = 8752666
47 + 8752619 = 8752666
53 + 8752613 = 8752666
113 + 8752553 = 8752666
239 + 8752427 = 8752666
479 + 8752187 = 8752666
509 + 8752157 = 8752666
599 + 8752067 = 8752666

Showing the first eight; more decompositions exist.
