Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702558, here are decompositions:

19 + 8702539 = 8702558
61 + 8702497 = 8702558
127 + 8702431 = 8702558
199 + 8702359 = 8702558
229 + 8702329 = 8702558
307 + 8702251 = 8702558
379 + 8702179 = 8702558
409 + 8702149 = 8702558

Showing the first eight; more decompositions exist.
