Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671156, here are decompositions:

5 + 8671151 = 8671156
23 + 8671133 = 8671156
29 + 8671127 = 8671156
59 + 8671097 = 8671156
89 + 8671067 = 8671156
149 + 8671007 = 8671156
167 + 8670989 = 8671156
269 + 8670887 = 8671156

Showing the first eight; more decompositions exist.
