Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751124, here are decompositions:

23 + 8751101 = 8751124
167 + 8750957 = 8751124
191 + 8750933 = 8751124
233 + 8750891 = 8751124
251 + 8750873 = 8751124
257 + 8750867 = 8751124
281 + 8750843 = 8751124
293 + 8750831 = 8751124

Showing the first eight; more decompositions exist.
