Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727664, here are decompositions:

5 + 8727659 = 8727664
41 + 8727623 = 8727664
53 + 8727611 = 8727664
167 + 8727497 = 8727664
233 + 8727431 = 8727664
251 + 8727413 = 8727664
347 + 8727317 = 8727664
401 + 8727263 = 8727664

Showing the first eight; more decompositions exist.
