Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42022, here are decompositions:

3 + 42019 = 42022
5 + 42017 = 42022
23 + 41999 = 42022
41 + 41981 = 42022
53 + 41969 = 42022
173 + 41849 = 42022
179 + 41843 = 42022
251 + 41771 = 42022

Showing the first eight; more decompositions exist.
