Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 80158, here are decompositions:

5 + 80153 = 80158
11 + 80147 = 80158
17 + 80141 = 80158
47 + 80111 = 80158
107 + 80051 = 80158
137 + 80021 = 80158
179 + 79979 = 80158
191 + 79967 = 80158

Showing the first eight; more decompositions exist.
