Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528540, here are decompositions:

13 + 528527 = 528540
29 + 528511 = 528540
31 + 528509 = 528540
53 + 528487 = 528540
71 + 528469 = 528540
107 + 528433 = 528540
127 + 528413 = 528540
137 + 528403 = 528540

Showing the first eight; more decompositions exist.
