Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528784, here are decompositions:

5 + 528779 = 528784
173 + 528611 = 528784
257 + 528527 = 528784
293 + 528491 = 528784
383 + 528401 = 528784
401 + 528383 = 528784
467 + 528317 = 528784
521 + 528263 = 528784

Showing the first eight; more decompositions exist.
