Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158238, here are decompositions:

5 + 158233 = 158238
7 + 158231 = 158238
11 + 158227 = 158238
29 + 158209 = 158238
37 + 158201 = 158238
97 + 158141 = 158238
109 + 158129 = 158238
167 + 158071 = 158238

Showing the first eight; more decompositions exist.
