Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520736, here are decompositions:

19 + 520717 = 520736
37 + 520699 = 520736
103 + 520633 = 520736
127 + 520609 = 520736
313 + 520423 = 520736
367 + 520369 = 520736
373 + 520363 = 520736
379 + 520357 = 520736

Showing the first eight; more decompositions exist.
