Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649618, here are decompositions:

7 + 8649611 = 8649618
37 + 8649581 = 8649618
97 + 8649521 = 8649618
101 + 8649517 = 8649618
127 + 8649491 = 8649618
139 + 8649479 = 8649618
149 + 8649469 = 8649618
151 + 8649467 = 8649618

Showing the first eight; more decompositions exist.
