Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528340, here are decompositions:

11 + 528329 = 528340
23 + 528317 = 528340
41 + 528299 = 528340
149 + 528191 = 528340
173 + 528167 = 528340
233 + 528107 = 528340
347 + 527993 = 528340
353 + 527987 = 528340

Showing the first eight; more decompositions exist.
