Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528418, here are decompositions:

5 + 528413 = 528418
17 + 528401 = 528418
89 + 528329 = 528418
101 + 528317 = 528418
227 + 528191 = 528418
251 + 528167 = 528418
281 + 528137 = 528418
311 + 528107 = 528418

Showing the first eight; more decompositions exist.
