Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520732, here are decompositions:

11 + 520721 = 520732
29 + 520703 = 520732
41 + 520691 = 520732
53 + 520679 = 520732
83 + 520649 = 520732
101 + 520631 = 520732
281 + 520451 = 520732
353 + 520379 = 520732

Showing the first eight; more decompositions exist.
