Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8717724, here are decompositions:

7 + 8717717 = 8717724
47 + 8717677 = 8717724
101 + 8717623 = 8717724
167 + 8717557 = 8717724
173 + 8717551 = 8717724
193 + 8717531 = 8717724
233 + 8717491 = 8717724
331 + 8717393 = 8717724

Showing the first eight; more decompositions exist.
