Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705842, here are decompositions:

11 + 8705831 = 8705842
83 + 8705759 = 8705842
113 + 8705729 = 8705842
269 + 8705573 = 8705842
281 + 8705561 = 8705842
293 + 8705549 = 8705842
311 + 8705531 = 8705842
359 + 8705483 = 8705842

Showing the first eight; more decompositions exist.
