Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666694, here are decompositions:

11 + 8666683 = 8666694
13 + 8666681 = 8666694
67 + 8666627 = 8666694
97 + 8666597 = 8666694
103 + 8666591 = 8666694
151 + 8666543 = 8666694
181 + 8666513 = 8666694
193 + 8666501 = 8666694

Showing the first eight; more decompositions exist.
