Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8609988, here are decompositions:

61 + 8609927 = 8609988
71 + 8609917 = 8609988
89 + 8609899 = 8609988
97 + 8609891 = 8609988
109 + 8609879 = 8609988
139 + 8609849 = 8609988
197 + 8609791 = 8609988
269 + 8609719 = 8609988

Showing the first eight; more decompositions exist.
