Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7224, here are decompositions:

5 + 7219 = 7224
11 + 7213 = 7224
13 + 7211 = 7224
17 + 7207 = 7224
31 + 7193 = 7224
37 + 7187 = 7224
47 + 7177 = 7224
73 + 7151 = 7224

Showing the first eight; more decompositions exist.
