Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520738, here are decompositions:

17 + 520721 = 520738
47 + 520691 = 520738
59 + 520679 = 520738
89 + 520649 = 520738
107 + 520631 = 520738
131 + 520607 = 520738
149 + 520589 = 520738
167 + 520571 = 520738

Showing the first eight; more decompositions exist.
