Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 511224, here are decompositions:

11 + 511213 = 511224
13 + 511211 = 511224
23 + 511201 = 511224
31 + 511193 = 511224
47 + 511177 = 511224
53 + 511171 = 511224
61 + 511163 = 511224
71 + 511153 = 511224

Showing the first eight; more decompositions exist.
