Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520744, here are decompositions:

23 + 520721 = 520744
41 + 520703 = 520744
53 + 520691 = 520744
113 + 520631 = 520744
137 + 520607 = 520744
173 + 520571 = 520744
197 + 520547 = 520744
293 + 520451 = 520744

Showing the first eight; more decompositions exist.
