Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691966, here are decompositions:

5 + 8691961 = 8691966
29 + 8691937 = 8691966
43 + 8691923 = 8691966
83 + 8691883 = 8691966
113 + 8691853 = 8691966
139 + 8691827 = 8691966
163 + 8691803 = 8691966
167 + 8691799 = 8691966

Showing the first eight; more decompositions exist.
