Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108160, here are decompositions:

29 + 108131 = 108160
53 + 108107 = 108160
71 + 108089 = 108160
137 + 108023 = 108160
149 + 108011 = 108160
179 + 107981 = 108160
233 + 107927 = 108160
257 + 107903 = 108160

Showing the first eight; more decompositions exist.
