Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687884, here are decompositions:

3 + 8687881 = 8687884
5 + 8687879 = 8687884
11 + 8687873 = 8687884
113 + 8687771 = 8687884
197 + 8687687 = 8687884
281 + 8687603 = 8687884
431 + 8687453 = 8687884
461 + 8687423 = 8687884

Showing the first eight; more decompositions exist.
