Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521224, here are decompositions:

23 + 521201 = 521224
47 + 521177 = 521224
71 + 521153 = 521224
173 + 521051 = 521224
257 + 520967 = 521224
281 + 520943 = 521224
311 + 520913 = 521224
383 + 520841 = 521224

Showing the first eight; more decompositions exist.
