Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72224, here are decompositions:

3 + 72221 = 72224
13 + 72211 = 72224
151 + 72073 = 72224
181 + 72043 = 72224
193 + 72031 = 72224
241 + 71983 = 72224
277 + 71947 = 72224
283 + 71941 = 72224

Showing the first eight; more decompositions exist.
