Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671138, here are decompositions:

5 + 8671133 = 8671138
11 + 8671127 = 8671138
41 + 8671097 = 8671138
71 + 8671067 = 8671138
107 + 8671031 = 8671138
131 + 8671007 = 8671138
149 + 8670989 = 8671138
191 + 8670947 = 8671138

Showing the first eight; more decompositions exist.
