Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516438, here are decompositions:

5 + 516433 = 516438
7 + 516431 = 516438
17 + 516421 = 516438
31 + 516407 = 516438
47 + 516391 = 516438
61 + 516377 = 516438
67 + 516371 = 516438
79 + 516359 = 516438

Showing the first eight; more decompositions exist.
