Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629818, here are decompositions:

5 + 8629813 = 8629818
47 + 8629771 = 8629818
79 + 8629739 = 8629818
107 + 8629711 = 8629818
137 + 8629681 = 8629818
139 + 8629679 = 8629818
157 + 8629661 = 8629818
167 + 8629651 = 8629818

Showing the first eight; more decompositions exist.
