Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627664, here are decompositions:

37 + 8627627 = 8627664
47 + 8627617 = 8627664
53 + 8627611 = 8627664
61 + 8627603 = 8627664
83 + 8627581 = 8627664
103 + 8627561 = 8627664
131 + 8627533 = 8627664
137 + 8627527 = 8627664

Showing the first eight; more decompositions exist.
