Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520680, here are decompositions:

31 + 520649 = 520680
47 + 520633 = 520680
59 + 520621 = 520680
71 + 520609 = 520680
73 + 520607 = 520680
109 + 520571 = 520680
113 + 520567 = 520680
131 + 520549 = 520680

Showing the first eight; more decompositions exist.
