Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666574, here are decompositions:

31 + 8666543 = 8666574
41 + 8666533 = 8666574
61 + 8666513 = 8666574
73 + 8666501 = 8666574
83 + 8666491 = 8666574
97 + 8666477 = 8666574
131 + 8666443 = 8666574
157 + 8666417 = 8666574

Showing the first eight; more decompositions exist.
