Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108188, here are decompositions:

61 + 108127 = 108188
79 + 108109 = 108188
109 + 108079 = 108188
127 + 108061 = 108188
151 + 108037 = 108188
181 + 108007 = 108188
307 + 107881 = 108188
331 + 107857 = 108188

Showing the first eight; more decompositions exist.
