Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656270, here are decompositions:

17 + 8656253 = 8656270
101 + 8656169 = 8656270
107 + 8656163 = 8656270
137 + 8656133 = 8656270
173 + 8656097 = 8656270
179 + 8656091 = 8656270
191 + 8656079 = 8656270
239 + 8656031 = 8656270

Showing the first eight; more decompositions exist.
