Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671198, here are decompositions:

5 + 8671193 = 8671198
47 + 8671151 = 8671198
71 + 8671127 = 8671198
101 + 8671097 = 8671198
131 + 8671067 = 8671198
167 + 8671031 = 8671198
191 + 8671007 = 8671198
251 + 8670947 = 8671198

Showing the first eight; more decompositions exist.
