Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528474, here are decompositions:

5 + 528469 = 528474
41 + 528433 = 528474
61 + 528413 = 528474
71 + 528403 = 528474
73 + 528401 = 528474
83 + 528391 = 528474
101 + 528373 = 528474
157 + 528317 = 528474

Showing the first eight; more decompositions exist.
