Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178108, here are decompositions:

5 + 178103 = 178108
17 + 178091 = 178108
41 + 178067 = 178108
71 + 178037 = 178108
107 + 178001 = 178108
179 + 177929 = 178108
191 + 177917 = 178108
269 + 177839 = 178108

Showing the first eight; more decompositions exist.
