Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670916, here are decompositions:

29 + 8670887 = 8670916
47 + 8670869 = 8670916
53 + 8670863 = 8670916
173 + 8670743 = 8670916
263 + 8670653 = 8670916
383 + 8670533 = 8670916
509 + 8670407 = 8670916
563 + 8670353 = 8670916

Showing the first eight; more decompositions exist.
