Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42556, here are decompositions:

23 + 42533 = 42556
47 + 42509 = 42556
83 + 42473 = 42556
89 + 42467 = 42556
113 + 42443 = 42556
149 + 42407 = 42556
197 + 42359 = 42556
233 + 42323 = 42556

Showing the first eight; more decompositions exist.
