Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538524, here are decompositions:

5 + 538519 = 538524
11 + 538513 = 538524
13 + 538511 = 538524
37 + 538487 = 538524
43 + 538481 = 538524
53 + 538471 = 538524
67 + 538457 = 538524
101 + 538423 = 538524

Showing the first eight; more decompositions exist.
