Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666724, here are decompositions:

13 + 8666711 = 8666724
41 + 8666683 = 8666724
43 + 8666681 = 8666724
97 + 8666627 = 8666724
127 + 8666597 = 8666724
181 + 8666543 = 8666724
191 + 8666533 = 8666724
211 + 8666513 = 8666724

Showing the first eight; more decompositions exist.
