Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16220, here are decompositions:

3 + 16217 = 16220
31 + 16189 = 16220
37 + 16183 = 16220
79 + 16141 = 16220
109 + 16111 = 16220
151 + 16069 = 16220
157 + 16063 = 16220
163 + 16057 = 16220

Showing the first eight; more decompositions exist.
