Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629020, here are decompositions:

11 + 8629009 = 8629020
17 + 8629003 = 8629020
47 + 8628973 = 8629020
53 + 8628967 = 8629020
83 + 8628937 = 8629020
97 + 8628923 = 8629020
107 + 8628913 = 8629020
131 + 8628889 = 8629020

Showing the first eight; more decompositions exist.
