Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 161358, here are decompositions:

17 + 161341 = 161358
19 + 161339 = 161358
137 + 161221 = 161358
157 + 161201 = 161358
191 + 161167 = 161358
199 + 161159 = 161358
271 + 161087 = 161358
311 + 161047 = 161358

Showing the first eight; more decompositions exist.
