Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687806, here are decompositions:

47 + 8687759 = 8687806
107 + 8687699 = 8687806
137 + 8687669 = 8687806
293 + 8687513 = 8687806
353 + 8687453 = 8687806
383 + 8687423 = 8687806
419 + 8687387 = 8687806
443 + 8687363 = 8687806

Showing the first eight; more decompositions exist.
