Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728894, here are decompositions:

11 + 8728883 = 8728894
71 + 8728823 = 8728894
107 + 8728787 = 8728894
137 + 8728757 = 8728894
173 + 8728721 = 8728894
467 + 8728427 = 8728894
521 + 8728373 = 8728894
563 + 8728331 = 8728894

Showing the first eight; more decompositions exist.
