Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655892, here are decompositions:

23 + 8655869 = 8655892
83 + 8655809 = 8655892
131 + 8655761 = 8655892
173 + 8655719 = 8655892
191 + 8655701 = 8655892
239 + 8655653 = 8655892
251 + 8655641 = 8655892
263 + 8655629 = 8655892

Showing the first eight; more decompositions exist.
