Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528844, here are decompositions:

11 + 528833 = 528844
23 + 528821 = 528844
53 + 528791 = 528844
137 + 528707 = 528844
233 + 528611 = 528844
317 + 528527 = 528844
353 + 528491 = 528844
431 + 528413 = 528844

Showing the first eight; more decompositions exist.
