Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513538, here are decompositions:

5 + 513533 = 513538
29 + 513509 = 513538
59 + 513479 = 513538
107 + 513431 = 513538
131 + 513407 = 513538
167 + 513371 = 513538
191 + 513347 = 513538
197 + 513341 = 513538

Showing the first eight; more decompositions exist.
