Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73228, here are decompositions:

47 + 73181 = 73228
101 + 73127 = 73228
107 + 73121 = 73228
137 + 73091 = 73228
149 + 73079 = 73228
167 + 73061 = 73228
191 + 73037 = 73228
251 + 72977 = 73228

Showing the first eight; more decompositions exist.
