Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528256, here are decompositions:

59 + 528197 = 528256
89 + 528167 = 528256
149 + 528107 = 528256
263 + 527993 = 528256
269 + 527987 = 528256
347 + 527909 = 528256
359 + 527897 = 528256
467 + 527789 = 528256

Showing the first eight; more decompositions exist.
