Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711138, here are decompositions:

67 + 8711071 = 8711138
127 + 8711011 = 8711138
181 + 8710957 = 8711138
199 + 8710939 = 8711138
229 + 8710909 = 8711138
367 + 8710771 = 8711138
409 + 8710729 = 8711138
421 + 8710717 = 8711138

Showing the first eight; more decompositions exist.
