Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047280, here are decompositions:

41 + 1047239 = 1047280
83 + 1047197 = 1047280
107 + 1047173 = 1047280
149 + 1047131 = 1047280
173 + 1047107 = 1047280
191 + 1047089 = 1047280
239 + 1047041 = 1047280
281 + 1046999 = 1047280

Showing the first eight; more decompositions exist.
