Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705458, here are decompositions:

5 + 8705453 = 8705458
17 + 8705441 = 8705458
29 + 8705429 = 8705458
59 + 8705399 = 8705458
89 + 8705369 = 8705458
107 + 8705351 = 8705458
197 + 8705261 = 8705458
239 + 8705219 = 8705458

Showing the first eight; more decompositions exist.
