Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 56442, here are decompositions:

5 + 56437 = 56442
11 + 56431 = 56442
41 + 56401 = 56442
59 + 56383 = 56442
73 + 56369 = 56442
83 + 56359 = 56442
109 + 56333 = 56442
131 + 56311 = 56442

Showing the first eight; more decompositions exist.
