Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666562, here are decompositions:

19 + 8666543 = 8666562
29 + 8666533 = 8666562
43 + 8666519 = 8666562
61 + 8666501 = 8666562
71 + 8666491 = 8666562
83 + 8666479 = 8666562
103 + 8666459 = 8666562
131 + 8666431 = 8666562

Showing the first eight; more decompositions exist.
