Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 65278, here are decompositions:

11 + 65267 = 65278
107 + 65171 = 65278
131 + 65147 = 65278
137 + 65141 = 65278
149 + 65129 = 65278
167 + 65111 = 65278
179 + 65099 = 65278
251 + 65027 = 65278

Showing the first eight; more decompositions exist.
