Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687180, here are decompositions:

31 + 8687149 = 8687180
181 + 8686999 = 8687180
199 + 8686981 = 8687180
373 + 8686807 = 8687180
613 + 8686567 = 8687180
709 + 8686471 = 8687180
811 + 8686369 = 8687180
883 + 8686297 = 8687180

Showing the first eight; more decompositions exist.
