Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687886, here are decompositions:

5 + 8687881 = 8687886
7 + 8687879 = 8687886
13 + 8687873 = 8687886
59 + 8687827 = 8687886
89 + 8687797 = 8687886
127 + 8687759 = 8687886
157 + 8687729 = 8687886
173 + 8687713 = 8687886

Showing the first eight; more decompositions exist.
