Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687880, here are decompositions:

7 + 8687873 = 8687880
53 + 8687827 = 8687880
83 + 8687797 = 8687880
109 + 8687771 = 8687880
151 + 8687729 = 8687880
167 + 8687713 = 8687880
181 + 8687699 = 8687880
193 + 8687687 = 8687880

Showing the first eight; more decompositions exist.
