Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687252, here are decompositions:

3 + 8687249 = 8687252
19 + 8687233 = 8687252
43 + 8687209 = 8687252
103 + 8687149 = 8687252
163 + 8687089 = 8687252
271 + 8686981 = 8687252
523 + 8686729 = 8687252
601 + 8686651 = 8687252

Showing the first eight; more decompositions exist.
