Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717800, here are decompositions:

17 + 8717783 = 8717800
53 + 8717747 = 8717800
59 + 8717741 = 8717800
83 + 8717717 = 8717800
167 + 8717633 = 8717800
269 + 8717531 = 8717800
587 + 8717213 = 8717800
599 + 8717201 = 8717800

Showing the first eight; more decompositions exist.
