Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717770, here are decompositions:

3 + 8717767 = 8717770
23 + 8717747 = 8717770
29 + 8717741 = 8717770
53 + 8717717 = 8717770
137 + 8717633 = 8717770
179 + 8717591 = 8717770
239 + 8717531 = 8717770
557 + 8717213 = 8717770

Showing the first eight; more decompositions exist.
