Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8703840, here are decompositions:

7 + 8703833 = 8703840
11 + 8703829 = 8703840
17 + 8703823 = 8703840
23 + 8703817 = 8703840
29 + 8703811 = 8703840
53 + 8703787 = 8703840
59 + 8703781 = 8703840
97 + 8703743 = 8703840

Showing the first eight; more decompositions exist.
