Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528500, here are decompositions:

13 + 528487 = 528500
31 + 528469 = 528500
67 + 528433 = 528500
97 + 528403 = 528500
109 + 528391 = 528500
127 + 528373 = 528500
211 + 528289 = 528500
277 + 528223 = 528500

Showing the first eight; more decompositions exist.
