Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8663988, here are decompositions:

19 + 8663969 = 8663988
29 + 8663959 = 8663988
89 + 8663899 = 8663988
127 + 8663861 = 8663988
167 + 8663821 = 8663988
181 + 8663807 = 8663988
191 + 8663797 = 8663988
211 + 8663777 = 8663988

Showing the first eight; more decompositions exist.
