Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671170, here are decompositions:

19 + 8671151 = 8671170
23 + 8671147 = 8671170
37 + 8671133 = 8671170
43 + 8671127 = 8671170
71 + 8671099 = 8671170
73 + 8671097 = 8671170
103 + 8671067 = 8671170
107 + 8671063 = 8671170

Showing the first eight; more decompositions exist.
