Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702510, here are decompositions:

7 + 8702503 = 8702510
13 + 8702497 = 8702510
79 + 8702431 = 8702510
139 + 8702371 = 8702510
151 + 8702359 = 8702510
181 + 8702329 = 8702510
199 + 8702311 = 8702510
331 + 8702179 = 8702510

Showing the first eight; more decompositions exist.
