Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158406, here are decompositions:

13 + 158393 = 158406
43 + 158363 = 158406
47 + 158359 = 158406
103 + 158303 = 158406
113 + 158293 = 158406
137 + 158269 = 158406
163 + 158243 = 158406
173 + 158233 = 158406

Showing the first eight; more decompositions exist.
