Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87288, here are decompositions:

7 + 87281 = 87288
11 + 87277 = 87288
31 + 87257 = 87288
37 + 87251 = 87288
67 + 87221 = 87288
101 + 87187 = 87288
107 + 87181 = 87288
109 + 87179 = 87288

Showing the first eight; more decompositions exist.
