Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711142, here are decompositions:

5 + 8711137 = 8711142
59 + 8711083 = 8711142
61 + 8711081 = 8711142
71 + 8711071 = 8711142
109 + 8711033 = 8711142
131 + 8711011 = 8711142
163 + 8710979 = 8711142
179 + 8710963 = 8711142

Showing the first eight; more decompositions exist.
