Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528718, here are decompositions:

11 + 528707 = 528718
59 + 528659 = 528718
89 + 528629 = 528718
107 + 528611 = 528718
191 + 528527 = 528718
227 + 528491 = 528718
317 + 528401 = 528718
389 + 528329 = 528718

Showing the first eight; more decompositions exist.
