Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103278, here are decompositions:

41 + 103237 = 103278
47 + 103231 = 103278
61 + 103217 = 103278
101 + 103177 = 103278
107 + 103171 = 103278
137 + 103141 = 103278
179 + 103099 = 103278
191 + 103087 = 103278

Showing the first eight; more decompositions exist.
