Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101664, here are decompositions:

11 + 101653 = 101664
23 + 101641 = 101664
37 + 101627 = 101664
53 + 101611 = 101664
61 + 101603 = 101664
83 + 101581 = 101664
103 + 101561 = 101664
127 + 101537 = 101664

Showing the first eight; more decompositions exist.
