Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72220, here are decompositions:

47 + 72173 = 72220
53 + 72167 = 72220
59 + 72161 = 72220
131 + 72089 = 72220
167 + 72053 = 72220
173 + 72047 = 72220
227 + 71993 = 72220
233 + 71987 = 72220

Showing the first eight; more decompositions exist.
