Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8699840, here are decompositions:

13 + 8699827 = 8699840
109 + 8699731 = 8699840
181 + 8699659 = 8699840
199 + 8699641 = 8699840
229 + 8699611 = 8699840
283 + 8699557 = 8699840
307 + 8699533 = 8699840
397 + 8699443 = 8699840

Showing the first eight; more decompositions exist.
