Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520516, here are decompositions:

83 + 520433 = 520516
89 + 520427 = 520516
107 + 520409 = 520516
137 + 520379 = 520516
167 + 520349 = 520516
443 + 520073 = 520516
449 + 520067 = 520516
569 + 519947 = 520516

Showing the first eight; more decompositions exist.
