Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77188, here are decompositions:

17 + 77171 = 77188
47 + 77141 = 77188
107 + 77081 = 77188
197 + 76991 = 77188
227 + 76961 = 77188
239 + 76949 = 77188
269 + 76919 = 77188
281 + 76907 = 77188

Showing the first eight; more decompositions exist.
