Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8599840, here are decompositions:

17 + 8599823 = 8599840
23 + 8599817 = 8599840
47 + 8599793 = 8599840
149 + 8599691 = 8599840
167 + 8599673 = 8599840
173 + 8599667 = 8599840
191 + 8599649 = 8599840
233 + 8599607 = 8599840

Showing the first eight; more decompositions exist.
