Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528874, here are decompositions:

11 + 528863 = 528874
41 + 528833 = 528874
53 + 528821 = 528874
83 + 528791 = 528874
167 + 528707 = 528874
251 + 528623 = 528874
263 + 528611 = 528874
347 + 528527 = 528874

Showing the first eight; more decompositions exist.
