Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700886, here are decompositions:

17 + 8700869 = 8700886
53 + 8700833 = 8700886
59 + 8700827 = 8700886
113 + 8700773 = 8700886
347 + 8700539 = 8700886
419 + 8700467 = 8700886
479 + 8700407 = 8700886
503 + 8700383 = 8700886

Showing the first eight; more decompositions exist.
