Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2224, here are decompositions:

3 + 2221 = 2224
11 + 2213 = 2224
17 + 2207 = 2224
71 + 2153 = 2224
83 + 2141 = 2224
113 + 2111 = 2224
137 + 2087 = 2224
197 + 2027 = 2224

Showing the first eight; more decompositions exist.
