Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728536, here are decompositions:

23 + 8728513 = 8728536
53 + 8728483 = 8728536
79 + 8728457 = 8728536
109 + 8728427 = 8728536
139 + 8728397 = 8728536
149 + 8728387 = 8728536
163 + 8728373 = 8728536
227 + 8728309 = 8728536

Showing the first eight; more decompositions exist.
