Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687782, here are decompositions:

11 + 8687771 = 8687782
23 + 8687759 = 8687782
53 + 8687729 = 8687782
83 + 8687699 = 8687782
113 + 8687669 = 8687782
179 + 8687603 = 8687782
269 + 8687513 = 8687782
353 + 8687429 = 8687782

Showing the first eight; more decompositions exist.
