Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108158, here are decompositions:

19 + 108139 = 108158
31 + 108127 = 108158
79 + 108079 = 108158
97 + 108061 = 108158
151 + 108007 = 108158
277 + 107881 = 108158
331 + 107827 = 108158
367 + 107791 = 108158

Showing the first eight; more decompositions exist.
