Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10220, here are decompositions:

43 + 10177 = 10220
61 + 10159 = 10220
79 + 10141 = 10220
109 + 10111 = 10220
127 + 10093 = 10220
151 + 10069 = 10220
181 + 10039 = 10220
211 + 10009 = 10220

Showing the first eight; more decompositions exist.
