Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518536, here are decompositions:

3 + 518533 = 518536
89 + 518447 = 518536
107 + 518429 = 518536
149 + 518387 = 518536
383 + 518153 = 518536
479 + 518057 = 518536
569 + 517967 = 518536
587 + 517949 = 518536

Showing the first eight; more decompositions exist.
