Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8716280, here are decompositions:

31 + 8716249 = 8716280
37 + 8716243 = 8716280
43 + 8716237 = 8716280
61 + 8716219 = 8716280
73 + 8716207 = 8716280
211 + 8716069 = 8716280
241 + 8716039 = 8716280
373 + 8715907 = 8716280

Showing the first eight; more decompositions exist.
