Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751288, here are decompositions:

31 + 8751257 = 8751288
37 + 8751251 = 8751288
67 + 8751221 = 8751288
107 + 8751181 = 8751288
131 + 8751157 = 8751288
137 + 8751151 = 8751288
149 + 8751139 = 8751288
191 + 8751097 = 8751288

Showing the first eight; more decompositions exist.
