Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513456, here are decompositions:

17 + 513439 = 513456
29 + 513427 = 513456
37 + 513419 = 513456
59 + 513397 = 513456
89 + 513367 = 513456
103 + 513353 = 513456
109 + 513347 = 513456
137 + 513319 = 513456

Showing the first eight; more decompositions exist.
