Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109664, here are decompositions:

3 + 109661 = 109664
43 + 109621 = 109664
67 + 109597 = 109664
97 + 109567 = 109664
127 + 109537 = 109664
157 + 109507 = 109664
193 + 109471 = 109664
211 + 109453 = 109664

Showing the first eight; more decompositions exist.
