Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513426, here are decompositions:

7 + 513419 = 513426
19 + 513407 = 513426
29 + 513397 = 513426
59 + 513367 = 513426
73 + 513353 = 513426
79 + 513347 = 513426
107 + 513319 = 513426
113 + 513313 = 513426

Showing the first eight; more decompositions exist.
