Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77168, here are decompositions:

31 + 77137 = 77168
67 + 77101 = 77168
127 + 77041 = 77168
139 + 77029 = 77168
151 + 77017 = 77168
331 + 76837 = 77168
337 + 76831 = 77168
349 + 76819 = 77168

Showing the first eight; more decompositions exist.
