Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42258, here are decompositions:

19 + 42239 = 42258
31 + 42227 = 42258
37 + 42221 = 42258
61 + 42197 = 42258
71 + 42187 = 42258
79 + 42179 = 42258
89 + 42169 = 42258
101 + 42157 = 42258

Showing the first eight; more decompositions exist.
