Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502220, here are decompositions:

3 + 502217 = 502220
79 + 502141 = 502220
127 + 502093 = 502220
139 + 502081 = 502220
157 + 502063 = 502220
163 + 502057 = 502220
181 + 502039 = 502220
223 + 501997 = 502220

Showing the first eight; more decompositions exist.
