Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619618, here are decompositions:

17 + 8619601 = 8619618
31 + 8619587 = 8619618
67 + 8619551 = 8619618
79 + 8619539 = 8619618
107 + 8619511 = 8619618
109 + 8619509 = 8619618
127 + 8619491 = 8619618
149 + 8619469 = 8619618

Showing the first eight; more decompositions exist.
