Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687080, here are decompositions:

11 + 8687069 = 8687080
53 + 8687027 = 8687080
179 + 8686901 = 8687080
191 + 8686889 = 8687080
197 + 8686883 = 8687080
239 + 8686841 = 8687080
251 + 8686829 = 8687080
359 + 8686721 = 8687080

Showing the first eight; more decompositions exist.
