Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705508, here are decompositions:

17 + 8705491 = 8705508
41 + 8705467 = 8705508
47 + 8705461 = 8705508
59 + 8705449 = 8705508
67 + 8705441 = 8705508
79 + 8705429 = 8705508
89 + 8705419 = 8705508
109 + 8705399 = 8705508

Showing the first eight; more decompositions exist.
