Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8711212, here are decompositions:

23 + 8711189 = 8711212
53 + 8711159 = 8711212
71 + 8711141 = 8711212
131 + 8711081 = 8711212
179 + 8711033 = 8711212
233 + 8710979 = 8711212
239 + 8710973 = 8711212
383 + 8710829 = 8711212

Showing the first eight; more decompositions exist.
