Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687004, here are decompositions:

5 + 8686999 = 8687004
23 + 8686981 = 8687004
43 + 8686961 = 8687004
103 + 8686901 = 8687004
127 + 8686877 = 8687004
163 + 8686841 = 8687004
197 + 8686807 = 8687004
283 + 8686721 = 8687004

Showing the first eight; more decompositions exist.
