Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717730, here are decompositions:

13 + 8717717 = 8717730
41 + 8717689 = 8717730
53 + 8717677 = 8717730
97 + 8717633 = 8717730
107 + 8717623 = 8717730
139 + 8717591 = 8717730
167 + 8717563 = 8717730
173 + 8717557 = 8717730

Showing the first eight; more decompositions exist.
