Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513638, here are decompositions:

7 + 513631 = 513638
109 + 513529 = 513638
127 + 513511 = 513638
157 + 513481 = 513638
199 + 513439 = 513638
211 + 513427 = 513638
241 + 513397 = 513638
271 + 513367 = 513638

Showing the first eight; more decompositions exist.
