Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728654, here are decompositions:

5 + 8728649 = 8728654
47 + 8728607 = 8728654
83 + 8728571 = 8728654
173 + 8728481 = 8728654
197 + 8728457 = 8728654
227 + 8728427 = 8728654
257 + 8728397 = 8728654
281 + 8728373 = 8728654

Showing the first eight; more decompositions exist.
