Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520716, here are decompositions:

13 + 520703 = 520716
17 + 520699 = 520716
37 + 520679 = 520716
67 + 520649 = 520716
83 + 520633 = 520716
107 + 520609 = 520716
109 + 520607 = 520716
127 + 520589 = 520716

Showing the first eight; more decompositions exist.
