Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747664, here are decompositions:

11 + 8747653 = 8747664
41 + 8747623 = 8747664
47 + 8747617 = 8747664
61 + 8747603 = 8747664
103 + 8747561 = 8747664
137 + 8747527 = 8747664
151 + 8747513 = 8747664
181 + 8747483 = 8747664

Showing the first eight; more decompositions exist.
