Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616566, here are decompositions:

3 + 8616563 = 8616566
19 + 8616547 = 8616566
67 + 8616499 = 8616566
73 + 8616493 = 8616566
109 + 8616457 = 8616566
193 + 8616373 = 8616566
229 + 8616337 = 8616566
349 + 8616217 = 8616566

Showing the first eight; more decompositions exist.
