Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711898, here are decompositions:

11 + 8711887 = 8711898
29 + 8711869 = 8711898
31 + 8711867 = 8711898
47 + 8711851 = 8711898
101 + 8711797 = 8711898
131 + 8711767 = 8711898
149 + 8711749 = 8711898
157 + 8711741 = 8711898

Showing the first eight; more decompositions exist.
