Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 504538, here are decompositions:

11 + 504527 = 504538
17 + 504521 = 504538
59 + 504479 = 504538
149 + 504389 = 504538
179 + 504359 = 504538
227 + 504311 = 504538
239 + 504299 = 504538
269 + 504269 = 504538

Showing the first eight; more decompositions exist.
