Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56538, here are decompositions:

5 + 56533 = 56538
7 + 56531 = 56538
11 + 56527 = 56538
19 + 56519 = 56538
29 + 56509 = 56538
37 + 56501 = 56538
59 + 56479 = 56538
61 + 56477 = 56538

Showing the first eight; more decompositions exist.
