Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711810, here are decompositions:

13 + 8711797 = 8711810
43 + 8711767 = 8711810
61 + 8711749 = 8711810
67 + 8711743 = 8711810
73 + 8711737 = 8711810
103 + 8711707 = 8711810
127 + 8711683 = 8711810
157 + 8711653 = 8711810

Showing the first eight; more decompositions exist.
