Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666810, here are decompositions:

3 + 8666807 = 8666810
13 + 8666797 = 8666810
37 + 8666773 = 8666810
43 + 8666767 = 8666810
127 + 8666683 = 8666810
277 + 8666533 = 8666810
331 + 8666479 = 8666810
367 + 8666443 = 8666810

Showing the first eight; more decompositions exist.
