Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42124, here are decompositions:

23 + 42101 = 42124
41 + 42083 = 42124
53 + 42071 = 42124
101 + 42023 = 42124
107 + 42017 = 42124
167 + 41957 = 42124
197 + 41927 = 42124
227 + 41897 = 42124

Showing the first eight; more decompositions exist.
