Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702470, here are decompositions:

11 + 8702459 = 8702470
59 + 8702411 = 8702470
83 + 8702387 = 8702470
137 + 8702333 = 8702470
191 + 8702279 = 8702470
239 + 8702231 = 8702470
263 + 8702207 = 8702470
281 + 8702189 = 8702470

Showing the first eight; more decompositions exist.
