Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513420, here are decompositions:

13 + 513407 = 513420
23 + 513397 = 513420
53 + 513367 = 513420
67 + 513353 = 513420
73 + 513347 = 513420
79 + 513341 = 513420
101 + 513319 = 513420
107 + 513313 = 513420

Showing the first eight; more decompositions exist.
