Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 536538, here are decompositions:

5 + 536533 = 536538
7 + 536531 = 536538
29 + 536509 = 536538
47 + 536491 = 536538
59 + 536479 = 536538
71 + 536467 = 536538
89 + 536449 = 536538
97 + 536441 = 536538

Showing the first eight; more decompositions exist.
