Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705518, here are decompositions:

11 + 8705507 = 8705518
89 + 8705429 = 8705518
149 + 8705369 = 8705518
167 + 8705351 = 8705518
257 + 8705261 = 8705518
281 + 8705237 = 8705518
347 + 8705171 = 8705518
359 + 8705159 = 8705518

Showing the first eight; more decompositions exist.
