Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702440, here are decompositions:

29 + 8702411 = 8702440
53 + 8702387 = 8702440
107 + 8702333 = 8702440
113 + 8702327 = 8702440
233 + 8702207 = 8702440
251 + 8702189 = 8702440
281 + 8702159 = 8702440
347 + 8702093 = 8702440

Showing the first eight; more decompositions exist.
