Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641010, here are decompositions:

3 + 8641007 = 8641010
43 + 8640967 = 8641010
61 + 8640949 = 8641010
127 + 8640883 = 8641010
139 + 8640871 = 8641010
151 + 8640859 = 8641010
193 + 8640817 = 8641010
211 + 8640799 = 8641010

Showing the first eight; more decompositions exist.
