Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15224, here are decompositions:

7 + 15217 = 15224
31 + 15193 = 15224
37 + 15187 = 15224
103 + 15121 = 15224
151 + 15073 = 15224
163 + 15061 = 15224
193 + 15031 = 15224
211 + 15013 = 15224

Showing the first eight; more decompositions exist.
