Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8224, here are decompositions:

3 + 8221 = 8224
5 + 8219 = 8224
53 + 8171 = 8224
101 + 8123 = 8224
107 + 8117 = 8224
113 + 8111 = 8224
131 + 8093 = 8224
137 + 8087 = 8224

Showing the first eight; more decompositions exist.
