Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666586, here are decompositions:

43 + 8666543 = 8666586
53 + 8666533 = 8666586
67 + 8666519 = 8666586
73 + 8666513 = 8666586
107 + 8666479 = 8666586
109 + 8666477 = 8666586
127 + 8666459 = 8666586
167 + 8666419 = 8666586

Showing the first eight; more decompositions exist.
