Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42224, here are decompositions:

3 + 42221 = 42224
31 + 42193 = 42224
37 + 42187 = 42224
43 + 42181 = 42224
67 + 42157 = 42224
151 + 42073 = 42224
163 + 42061 = 42224
181 + 42043 = 42224

Showing the first eight; more decompositions exist.
