Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646988, here are decompositions:

17 + 8646971 = 8646988
41 + 8646947 = 8646988
59 + 8646929 = 8646988
89 + 8646899 = 8646988
137 + 8646851 = 8646988
167 + 8646821 = 8646988
269 + 8646719 = 8646988
281 + 8646707 = 8646988

Showing the first eight; more decompositions exist.
