Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711786, here are decompositions:

3 + 8711783 = 8711786
19 + 8711767 = 8711786
37 + 8711749 = 8711786
43 + 8711743 = 8711786
67 + 8711719 = 8711786
79 + 8711707 = 8711786
103 + 8711683 = 8711786
409 + 8711377 = 8711786

Showing the first eight; more decompositions exist.
