Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108320, here are decompositions:

19 + 108301 = 108320
31 + 108289 = 108320
73 + 108247 = 108320
97 + 108223 = 108320
103 + 108217 = 108320
109 + 108211 = 108320
127 + 108193 = 108320
181 + 108139 = 108320

Showing the first eight; more decompositions exist.
