Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751228, here are decompositions:

7 + 8751221 = 8751228
47 + 8751181 = 8751228
71 + 8751157 = 8751228
89 + 8751139 = 8751228
127 + 8751101 = 8751228
131 + 8751097 = 8751228
137 + 8751091 = 8751228
139 + 8751089 = 8751228

Showing the first eight; more decompositions exist.
