Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727918, here are decompositions:

5 + 8727913 = 8727918
11 + 8727907 = 8727918
19 + 8727899 = 8727918
47 + 8727871 = 8727918
61 + 8727857 = 8727918
109 + 8727809 = 8727918
127 + 8727791 = 8727918
139 + 8727779 = 8727918

Showing the first eight; more decompositions exist.
