Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8732666, here are decompositions:

13 + 8732653 = 8732666
67 + 8732599 = 8732666
73 + 8732593 = 8732666
193 + 8732473 = 8732666
367 + 8732299 = 8732666
409 + 8732257 = 8732666
457 + 8732209 = 8732666
619 + 8732047 = 8732666

Showing the first eight; more decompositions exist.
