Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513556, here are decompositions:

23 + 513533 = 513556
47 + 513509 = 513556
83 + 513473 = 513556
137 + 513419 = 513556
149 + 513407 = 513556
317 + 513239 = 513556
353 + 513203 = 513556
383 + 513173 = 513556

Showing the first eight; more decompositions exist.
