Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728948, here are decompositions:

5 + 8728943 = 8728948
47 + 8728901 = 8728948
191 + 8728757 = 8728948
227 + 8728721 = 8728948
257 + 8728691 = 8728948
269 + 8728679 = 8728948
467 + 8728481 = 8728948
491 + 8728457 = 8728948

Showing the first eight; more decompositions exist.
