Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520772, here are decompositions:

13 + 520759 = 520772
73 + 520699 = 520772
139 + 520633 = 520772
151 + 520621 = 520772
163 + 520609 = 520772
223 + 520549 = 520772
349 + 520423 = 520772
379 + 520393 = 520772

Showing the first eight; more decompositions exist.
