Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42238, here are decompositions:

11 + 42227 = 42238
17 + 42221 = 42238
29 + 42209 = 42238
41 + 42197 = 42238
59 + 42179 = 42238
107 + 42131 = 42238
137 + 42101 = 42238
149 + 42089 = 42238

Showing the first eight; more decompositions exist.
