Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655886, here are decompositions:

3 + 8655883 = 8655886
17 + 8655869 = 8655886
137 + 8655749 = 8655886
167 + 8655719 = 8655886
179 + 8655707 = 8655886
233 + 8655653 = 8655886
257 + 8655629 = 8655886
263 + 8655623 = 8655886

Showing the first eight; more decompositions exist.
