Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538582, here are decompositions:

3 + 538579 = 538582
29 + 538553 = 538582
53 + 538529 = 538582
59 + 538523 = 538582
71 + 538511 = 538582
101 + 538481 = 538582
251 + 538331 = 538582
281 + 538301 = 538582

Showing the first eight; more decompositions exist.
