Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513508, here are decompositions:

29 + 513479 = 513508
89 + 513419 = 513508
101 + 513407 = 513508
137 + 513371 = 513508
167 + 513341 = 513508
197 + 513311 = 513508
239 + 513269 = 513508
251 + 513257 = 513508

Showing the first eight; more decompositions exist.
