Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751156, here are decompositions:

5 + 8751151 = 8751156
13 + 8751143 = 8751156
17 + 8751139 = 8751156
59 + 8751097 = 8751156
67 + 8751089 = 8751156
149 + 8751007 = 8751156
199 + 8750957 = 8751156
223 + 8750933 = 8751156

Showing the first eight; more decompositions exist.
