Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705566, here are decompositions:

5 + 8705561 = 8705566
17 + 8705549 = 8705566
47 + 8705519 = 8705566
59 + 8705507 = 8705566
83 + 8705483 = 8705566
113 + 8705453 = 8705566
137 + 8705429 = 8705566
167 + 8705399 = 8705566

Showing the first eight; more decompositions exist.
