Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628630, here are decompositions:

7 + 8628623 = 8628630
29 + 8628601 = 8628630
79 + 8628551 = 8628630
83 + 8628547 = 8628630
137 + 8628493 = 8628630
149 + 8628481 = 8628630
151 + 8628479 = 8628630
167 + 8628463 = 8628630

Showing the first eight; more decompositions exist.
