Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666540, here are decompositions:

7 + 8666533 = 8666540
61 + 8666479 = 8666540
97 + 8666443 = 8666540
109 + 8666431 = 8666540
193 + 8666347 = 8666540
271 + 8666269 = 8666540
367 + 8666173 = 8666540
373 + 8666167 = 8666540

Showing the first eight; more decompositions exist.
