Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687540, here are decompositions:

19 + 8687521 = 8687540
61 + 8687479 = 8687540
73 + 8687467 = 8687540
79 + 8687461 = 8687540
139 + 8687401 = 8687540
157 + 8687383 = 8687540
181 + 8687359 = 8687540
223 + 8687317 = 8687540

Showing the first eight; more decompositions exist.
