Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727900, here are decompositions:

29 + 8727871 = 8727900
43 + 8727857 = 8727900
109 + 8727791 = 8727900
127 + 8727773 = 8727900
173 + 8727727 = 8727900
199 + 8727701 = 8727900
211 + 8727689 = 8727900
227 + 8727673 = 8727900

Showing the first eight; more decompositions exist.
