Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520740, here are decompositions:

19 + 520721 = 520740
23 + 520717 = 520740
37 + 520703 = 520740
41 + 520699 = 520740
61 + 520679 = 520740
107 + 520633 = 520740
109 + 520631 = 520740
131 + 520609 = 520740

Showing the first eight; more decompositions exist.
