Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518072, here are decompositions:

13 + 518059 = 518072
73 + 517999 = 518072
199 + 517873 = 518072
211 + 517861 = 518072
241 + 517831 = 518072
433 + 517639 = 518072
463 + 517609 = 518072
523 + 517549 = 518072

Showing the first eight; more decompositions exist.
