Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513886, here are decompositions:

5 + 513881 = 513886
47 + 513839 = 513886
137 + 513749 = 513886
167 + 513719 = 513886
293 + 513593 = 513886
353 + 513533 = 513886
467 + 513419 = 513886
479 + 513407 = 513886

Showing the first eight; more decompositions exist.
