Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727822, here are decompositions:

13 + 8727809 = 8727822
31 + 8727791 = 8727822
43 + 8727779 = 8727822
149 + 8727673 = 8727822
163 + 8727659 = 8727822
179 + 8727643 = 8727822
199 + 8727623 = 8727822
211 + 8727611 = 8727822

Showing the first eight; more decompositions exist.
