Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728794, here are decompositions:

7 + 8728787 = 8728794
37 + 8728757 = 8728794
73 + 8728721 = 8728794
83 + 8728711 = 8728794
103 + 8728691 = 8728794
131 + 8728663 = 8728794
167 + 8728627 = 8728794
197 + 8728597 = 8728794

Showing the first eight; more decompositions exist.
