Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649630, here are decompositions:

7 + 8649623 = 8649630
19 + 8649611 = 8649630
97 + 8649533 = 8649630
109 + 8649521 = 8649630
113 + 8649517 = 8649630
139 + 8649491 = 8649630
151 + 8649479 = 8649630
163 + 8649467 = 8649630

Showing the first eight; more decompositions exist.
