Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8610966, here are decompositions:

5 + 8610961 = 8610966
29 + 8610937 = 8610966
47 + 8610919 = 8610966
53 + 8610913 = 8610966
73 + 8610893 = 8610966
103 + 8610863 = 8610966
137 + 8610829 = 8610966
139 + 8610827 = 8610966

Showing the first eight; more decompositions exist.
