Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500428, here are decompositions:

11 + 500417 = 500428
59 + 500369 = 500428
107 + 500321 = 500428
179 + 500249 = 500428
191 + 500237 = 500428
197 + 500231 = 500428
251 + 500177 = 500428
317 + 500111 = 500428

Showing the first eight; more decompositions exist.
