Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687872, here are decompositions:

101 + 8687771 = 8687872
113 + 8687759 = 8687872
173 + 8687699 = 8687872
269 + 8687603 = 8687872
359 + 8687513 = 8687872
419 + 8687453 = 8687872
443 + 8687429 = 8687872
449 + 8687423 = 8687872

Showing the first eight; more decompositions exist.
