Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73220, here are decompositions:

31 + 73189 = 73220
79 + 73141 = 73220
157 + 73063 = 73220
181 + 73039 = 73220
211 + 73009 = 73220
223 + 72997 = 73220
271 + 72949 = 73220
283 + 72937 = 73220

Showing the first eight; more decompositions exist.
