Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8652666, here are decompositions:

5 + 8652661 = 8652666
7 + 8652659 = 8652666
19 + 8652647 = 8652666
37 + 8652629 = 8652666
53 + 8652613 = 8652666
73 + 8652593 = 8652666
79 + 8652587 = 8652666
103 + 8652563 = 8652666

Showing the first eight; more decompositions exist.
