Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538540, here are decompositions:

11 + 538529 = 538540
17 + 538523 = 538540
29 + 538511 = 538540
53 + 538487 = 538540
59 + 538481 = 538540
83 + 538457 = 538540
173 + 538367 = 538540
239 + 538301 = 538540

Showing the first eight; more decompositions exist.
