Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18656, here are decompositions:

19 + 18637 = 18656
73 + 18583 = 18656
103 + 18553 = 18656
139 + 18517 = 18656
163 + 18493 = 18656
199 + 18457 = 18656
223 + 18433 = 18656
229 + 18427 = 18656

Showing the first eight; more decompositions exist.
