Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687318, here are decompositions:

19 + 8687299 = 8687318
109 + 8687209 = 8687318
229 + 8687089 = 8687318
337 + 8686981 = 8687318
631 + 8686687 = 8687318
751 + 8686567 = 8687318
859 + 8686459 = 8687318
1009 + 8686309 = 8687318

Showing the first eight; more decompositions exist.
