Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 512828, here are decompositions:

7 + 512821 = 512828
31 + 512797 = 512828
61 + 512767 = 512828
67 + 512761 = 512828
157 + 512671 = 512828
307 + 512521 = 512828
331 + 512497 = 512828
409 + 512419 = 512828

Showing the first eight; more decompositions exist.
