Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102224, here are decompositions:

7 + 102217 = 102224
43 + 102181 = 102224
103 + 102121 = 102224
163 + 102061 = 102224
181 + 102043 = 102224
193 + 102031 = 102224
211 + 102013 = 102224
223 + 102001 = 102224

Showing the first eight; more decompositions exist.
