Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616988, here are decompositions:

41 + 8616947 = 8616988
71 + 8616917 = 8616988
101 + 8616887 = 8616988
167 + 8616821 = 8616988
179 + 8616809 = 8616988
227 + 8616761 = 8616988
269 + 8616719 = 8616988
389 + 8616599 = 8616988

Showing the first eight; more decompositions exist.
