Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672988, here are decompositions:

19 + 8672969 = 8672988
41 + 8672947 = 8672988
61 + 8672927 = 8672988
97 + 8672891 = 8672988
127 + 8672861 = 8672988
157 + 8672831 = 8672988
167 + 8672821 = 8672988
197 + 8672791 = 8672988

Showing the first eight; more decompositions exist.
