Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6220, here are decompositions:

3 + 6217 = 6220
17 + 6203 = 6220
23 + 6197 = 6220
47 + 6173 = 6220
89 + 6131 = 6220
107 + 6113 = 6220
131 + 6089 = 6220
167 + 6053 = 6220

Showing the first eight; more decompositions exist.
