Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513494, here are decompositions:

13 + 513481 = 513494
67 + 513427 = 513494
97 + 513397 = 513494
127 + 513367 = 513494
181 + 513313 = 513494
211 + 513283 = 513494
337 + 513157 = 513494
463 + 513031 = 513494

Showing the first eight; more decompositions exist.
