Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 77278, here are decompositions:

11 + 77267 = 77278
17 + 77261 = 77278
29 + 77249 = 77278
41 + 77237 = 77278
107 + 77171 = 77278
137 + 77141 = 77278
197 + 77081 = 77278
317 + 76961 = 77278

Showing the first eight; more decompositions exist.
