Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188108, here are decompositions:

79 + 188029 = 188108
97 + 188011 = 188108
157 + 187951 = 188108
181 + 187927 = 188108
199 + 187909 = 188108
211 + 187897 = 188108
397 + 187711 = 188108
409 + 187699 = 188108

Showing the first eight; more decompositions exist.
