Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687706, here are decompositions:

7 + 8687699 = 8687706
19 + 8687687 = 8687706
37 + 8687669 = 8687706
47 + 8687659 = 8687706
103 + 8687603 = 8687706
107 + 8687599 = 8687706
193 + 8687513 = 8687706
227 + 8687479 = 8687706

Showing the first eight; more decompositions exist.
