Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717790, here are decompositions:

7 + 8717783 = 8717790
17 + 8717773 = 8717790
23 + 8717767 = 8717790
41 + 8717749 = 8717790
43 + 8717747 = 8717790
47 + 8717743 = 8717790
73 + 8717717 = 8717790
101 + 8717689 = 8717790

Showing the first eight; more decompositions exist.
