Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8676990, here are decompositions:

17 + 8676973 = 8676990
19 + 8676971 = 8676990
41 + 8676949 = 8676990
53 + 8676937 = 8676990
97 + 8676893 = 8676990
107 + 8676883 = 8676990
163 + 8676827 = 8676990
191 + 8676799 = 8676990

Showing the first eight; more decompositions exist.
