Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513378, here are decompositions:

7 + 513371 = 513378
11 + 513367 = 513378
31 + 513347 = 513378
37 + 513341 = 513378
59 + 513319 = 513378
67 + 513311 = 513378
71 + 513307 = 513378
101 + 513277 = 513378

Showing the first eight; more decompositions exist.
