Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728886, here are decompositions:

3 + 8728883 = 8728886
37 + 8728849 = 8728886
79 + 8728807 = 8728886
223 + 8728663 = 8728886
277 + 8728609 = 8728886
307 + 8728579 = 8728886
337 + 8728549 = 8728886
373 + 8728513 = 8728886

Showing the first eight; more decompositions exist.
