Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711900, here are decompositions:

3 + 8711897 = 8711900
13 + 8711887 = 8711900
31 + 8711869 = 8711900
37 + 8711863 = 8711900
79 + 8711821 = 8711900
103 + 8711797 = 8711900
151 + 8711749 = 8711900
157 + 8711743 = 8711900

Showing the first eight; more decompositions exist.
