Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728960, here are decompositions:

17 + 8728943 = 8728960
59 + 8728901 = 8728960
137 + 8728823 = 8728960
173 + 8728787 = 8728960
239 + 8728721 = 8728960
269 + 8728691 = 8728960
281 + 8728679 = 8728960
311 + 8728649 = 8728960

Showing the first eight; more decompositions exist.
