Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513344, here are decompositions:

3 + 513341 = 513344
31 + 513313 = 513344
37 + 513307 = 513344
61 + 513283 = 513344
67 + 513277 = 513344
241 + 513103 = 513344
277 + 513067 = 513344
313 + 513031 = 513344

Showing the first eight; more decompositions exist.
