Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700288, here are decompositions:

5 + 8700283 = 8700288
7 + 8700281 = 8700288
31 + 8700257 = 8700288
127 + 8700161 = 8700288
167 + 8700121 = 8700288
229 + 8700059 = 8700288
241 + 8700047 = 8700288
251 + 8700037 = 8700288

Showing the first eight; more decompositions exist.
