Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171108, here are decompositions:

5 + 171103 = 171108
17 + 171091 = 171108
29 + 171079 = 171108
31 + 171077 = 171108
59 + 171049 = 171108
61 + 171047 = 171108
79 + 171029 = 171108
101 + 171007 = 171108

Showing the first eight; more decompositions exist.
