Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103280, here are decompositions:

43 + 103237 = 103280
97 + 103183 = 103280
103 + 103177 = 103280
109 + 103171 = 103280
139 + 103141 = 103280
157 + 103123 = 103280
181 + 103099 = 103280
193 + 103087 = 103280

Showing the first eight; more decompositions exist.
