Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513658, here are decompositions:

17 + 513641 = 513658
149 + 513509 = 513658
179 + 513479 = 513658
227 + 513431 = 513658
239 + 513419 = 513658
251 + 513407 = 513658
311 + 513347 = 513658
317 + 513341 = 513658

Showing the first eight; more decompositions exist.
