Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600986, here are decompositions:

29 + 8600957 = 8600986
89 + 8600897 = 8600986
167 + 8600819 = 8600986
179 + 8600807 = 8600986
197 + 8600789 = 8600986
239 + 8600747 = 8600986
269 + 8600717 = 8600986
347 + 8600639 = 8600986

Showing the first eight; more decompositions exist.
