Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700928, here are decompositions:

17 + 8700911 = 8700928
59 + 8700869 = 8700928
101 + 8700827 = 8700928
347 + 8700581 = 8700928
389 + 8700539 = 8700928
461 + 8700467 = 8700928
479 + 8700449 = 8700928
521 + 8700407 = 8700928

Showing the first eight; more decompositions exist.
