Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528508, here are decompositions:

17 + 528491 = 528508
89 + 528419 = 528508
107 + 528401 = 528508
179 + 528329 = 528508
191 + 528317 = 528508
311 + 528197 = 528508
317 + 528191 = 528508
401 + 528107 = 528508

Showing the first eight; more decompositions exist.
