Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728744, here are decompositions:

23 + 8728721 = 8728744
53 + 8728691 = 8728744
137 + 8728607 = 8728744
173 + 8728571 = 8728744
263 + 8728481 = 8728744
317 + 8728427 = 8728744
347 + 8728397 = 8728744
503 + 8728241 = 8728744

Showing the first eight; more decompositions exist.
