Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701186, here are decompositions:

23 + 8701163 = 8701186
173 + 8701013 = 8701186
233 + 8700953 = 8701186
239 + 8700947 = 8701186
293 + 8700893 = 8701186
317 + 8700869 = 8701186
353 + 8700833 = 8701186
359 + 8700827 = 8701186

Showing the first eight; more decompositions exist.
