Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520832, here are decompositions:

19 + 520813 = 520832
73 + 520759 = 520832
199 + 520633 = 520832
211 + 520621 = 520832
223 + 520609 = 520832
283 + 520549 = 520832
409 + 520423 = 520832
421 + 520411 = 520832

Showing the first eight; more decompositions exist.
