Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656988, here are decompositions:

97 + 8656891 = 8656988
139 + 8656849 = 8656988
157 + 8656831 = 8656988
181 + 8656807 = 8656988
229 + 8656759 = 8656988
577 + 8656411 = 8656988
619 + 8656369 = 8656988
631 + 8656357 = 8656988

Showing the first eight; more decompositions exist.
