Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687670, here are decompositions:

11 + 8687659 = 8687670
29 + 8687641 = 8687670
67 + 8687603 = 8687670
71 + 8687599 = 8687670
83 + 8687587 = 8687670
149 + 8687521 = 8687670
157 + 8687513 = 8687670
191 + 8687479 = 8687670

Showing the first eight; more decompositions exist.
