Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528516, here are decompositions:

5 + 528511 = 528516
7 + 528509 = 528516
29 + 528487 = 528516
47 + 528469 = 528516
83 + 528433 = 528516
97 + 528419 = 528516
103 + 528413 = 528516
113 + 528403 = 528516

Showing the first eight; more decompositions exist.
