Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727724, here are decompositions:

23 + 8727701 = 8727724
101 + 8727623 = 8727724
113 + 8727611 = 8727724
227 + 8727497 = 8727724
293 + 8727431 = 8727724
311 + 8727413 = 8727724
461 + 8727263 = 8727724
563 + 8727161 = 8727724

Showing the first eight; more decompositions exist.
