Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513550, here are decompositions:

17 + 513533 = 513550
41 + 513509 = 513550
71 + 513479 = 513550
131 + 513419 = 513550
179 + 513371 = 513550
197 + 513353 = 513550
239 + 513311 = 513550
281 + 513269 = 513550

Showing the first eight; more decompositions exist.
