Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528512, here are decompositions:

3 + 528509 = 528512
43 + 528469 = 528512
79 + 528433 = 528512
109 + 528403 = 528512
139 + 528373 = 528512
199 + 528313 = 528512
223 + 528289 = 528512
349 + 528163 = 528512

Showing the first eight; more decompositions exist.
