Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728576, here are decompositions:

5 + 8728571 = 8728576
149 + 8728427 = 8728576
179 + 8728397 = 8728576
383 + 8728193 = 8728576
503 + 8728073 = 8728576
587 + 8727989 = 8728576
677 + 8727899 = 8728576
719 + 8727857 = 8728576

Showing the first eight; more decompositions exist.
