Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666940, here are decompositions:

13 + 8666927 = 8666940
59 + 8666881 = 8666940
101 + 8666839 = 8666940
131 + 8666809 = 8666940
157 + 8666783 = 8666940
167 + 8666773 = 8666940
173 + 8666767 = 8666940
193 + 8666747 = 8666940

Showing the first eight; more decompositions exist.
