Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751280, here are decompositions:

23 + 8751257 = 8751280
29 + 8751251 = 8751280
47 + 8751233 = 8751280
59 + 8751221 = 8751280
107 + 8751173 = 8751280
137 + 8751143 = 8751280
179 + 8751101 = 8751280
191 + 8751089 = 8751280

Showing the first eight; more decompositions exist.
