Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717928, here are decompositions:

19 + 8717909 = 8717928
47 + 8717881 = 8717928
59 + 8717869 = 8717928
61 + 8717867 = 8717928
67 + 8717861 = 8717928
71 + 8717857 = 8717928
137 + 8717791 = 8717928
179 + 8717749 = 8717928

Showing the first eight; more decompositions exist.
