Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687012, here are decompositions:

13 + 8686999 = 8687012
31 + 8686981 = 8687012
283 + 8686729 = 8687012
541 + 8686471 = 8687012
643 + 8686369 = 8687012
739 + 8686273 = 8687012
823 + 8686189 = 8687012
853 + 8686159 = 8687012

Showing the first eight; more decompositions exist.
