Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7220, here are decompositions:

7 + 7213 = 7220
13 + 7207 = 7220
43 + 7177 = 7220
61 + 7159 = 7220
151 + 7069 = 7220
163 + 7057 = 7220
181 + 7039 = 7220
193 + 7027 = 7220

Showing the first eight; more decompositions exist.
