Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629620, here are decompositions:

7 + 8629613 = 8629620
23 + 8629597 = 8629620
37 + 8629583 = 8629620
59 + 8629561 = 8629620
113 + 8629507 = 8629620
137 + 8629483 = 8629620
173 + 8629447 = 8629620
179 + 8629441 = 8629620

Showing the first eight; more decompositions exist.
