Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103220, here are decompositions:

3 + 103217 = 103220
37 + 103183 = 103220
43 + 103177 = 103220
79 + 103141 = 103220
97 + 103123 = 103220
127 + 103093 = 103220
151 + 103069 = 103220
307 + 102913 = 103220

Showing the first eight; more decompositions exist.
