Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56542, here are decompositions:

11 + 56531 = 56542
23 + 56519 = 56542
41 + 56501 = 56542
53 + 56489 = 56542
89 + 56453 = 56542
149 + 56393 = 56542
173 + 56369 = 56542
293 + 56249 = 56542

Showing the first eight; more decompositions exist.
