Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629664, here are decompositions:

3 + 8629661 = 8629664
13 + 8629651 = 8629664
67 + 8629597 = 8629664
103 + 8629561 = 8629664
157 + 8629507 = 8629664
181 + 8629483 = 8629664
223 + 8629441 = 8629664
331 + 8629333 = 8629664

Showing the first eight; more decompositions exist.
