Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629928, here are decompositions:

19 + 8629909 = 8629928
37 + 8629891 = 8629928
61 + 8629867 = 8629928
157 + 8629771 = 8629928
277 + 8629651 = 8629928
331 + 8629597 = 8629928
367 + 8629561 = 8629928
421 + 8629507 = 8629928

Showing the first eight; more decompositions exist.
