Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705500, here are decompositions:

17 + 8705483 = 8705500
47 + 8705453 = 8705500
59 + 8705441 = 8705500
71 + 8705429 = 8705500
101 + 8705399 = 8705500
131 + 8705369 = 8705500
149 + 8705351 = 8705500
239 + 8705261 = 8705500

Showing the first eight; more decompositions exist.
