Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158390, here are decompositions:

19 + 158371 = 158390
31 + 158359 = 158390
61 + 158329 = 158390
97 + 158293 = 158390
157 + 158233 = 158390
163 + 158227 = 158390
181 + 158209 = 158390
229 + 158161 = 158390

Showing the first eight; more decompositions exist.
