Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727984, here are decompositions:

47 + 8727937 = 8727984
53 + 8727931 = 8727984
71 + 8727913 = 8727984
113 + 8727871 = 8727984
127 + 8727857 = 8727984
193 + 8727791 = 8727984
211 + 8727773 = 8727984
227 + 8727757 = 8727984

Showing the first eight; more decompositions exist.
