Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 502528, here are decompositions:

11 + 502517 = 502528
29 + 502499 = 502528
41 + 502487 = 502528
107 + 502421 = 502528
227 + 502301 = 502528
251 + 502277 = 502528
269 + 502259 = 502528
281 + 502247 = 502528

Showing the first eight; more decompositions exist.
