Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158384, here are decompositions:

13 + 158371 = 158384
43 + 158341 = 158384
151 + 158233 = 158384
157 + 158227 = 158384
223 + 158161 = 158384
241 + 158143 = 158384
271 + 158113 = 158384
307 + 158077 = 158384

Showing the first eight; more decompositions exist.
