Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702428, here are decompositions:

17 + 8702411 = 8702428
41 + 8702387 = 8702428
101 + 8702327 = 8702428
149 + 8702279 = 8702428
197 + 8702231 = 8702428
239 + 8702189 = 8702428
269 + 8702159 = 8702428
419 + 8702009 = 8702428

Showing the first eight; more decompositions exist.
