Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520650, here are decompositions:

17 + 520633 = 520650
19 + 520631 = 520650
29 + 520621 = 520650
41 + 520609 = 520650
43 + 520607 = 520650
61 + 520589 = 520650
79 + 520571 = 520650
83 + 520567 = 520650

Showing the first eight; more decompositions exist.
