Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1007280, here are decompositions:

31 + 1007249 = 1007280
37 + 1007243 = 1007280
101 + 1007179 = 1007280
107 + 1007173 = 1007280
151 + 1007129 = 1007280
163 + 1007117 = 1007280
181 + 1007099 = 1007280
191 + 1007089 = 1007280

Showing the first eight; more decompositions exist.
