Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671210, here are decompositions:

17 + 8671193 = 8671210
59 + 8671151 = 8671210
83 + 8671127 = 8671210
113 + 8671097 = 8671210
179 + 8671031 = 8671210
263 + 8670947 = 8671210
269 + 8670941 = 8671210
347 + 8670863 = 8671210

Showing the first eight; more decompositions exist.
