Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8619666, here are decompositions:

5 + 8619661 = 8619666
17 + 8619649 = 8619666
43 + 8619623 = 8619666
73 + 8619593 = 8619666
79 + 8619587 = 8619666
127 + 8619539 = 8619666
157 + 8619509 = 8619666
193 + 8619473 = 8619666

Showing the first eight; more decompositions exist.
