Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77224, here are decompositions:

11 + 77213 = 77224
23 + 77201 = 77224
53 + 77171 = 77224
71 + 77153 = 77224
83 + 77141 = 77224
131 + 77093 = 77224
233 + 76991 = 77224
263 + 76961 = 77224

Showing the first eight; more decompositions exist.
