Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638764, here are decompositions:

31 + 8638733 = 8638764
37 + 8638727 = 8638764
67 + 8638697 = 8638764
73 + 8638691 = 8638764
103 + 8638661 = 8638764
131 + 8638633 = 8638764
137 + 8638627 = 8638764
181 + 8638583 = 8638764

Showing the first eight; more decompositions exist.
