Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8606840, here are decompositions:

13 + 8606827 = 8606840
43 + 8606797 = 8606840
61 + 8606779 = 8606840
103 + 8606737 = 8606840
241 + 8606599 = 8606840
283 + 8606557 = 8606840
313 + 8606527 = 8606840
331 + 8606509 = 8606840

Showing the first eight; more decompositions exist.
