Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751040, here are decompositions:

3 + 8751037 = 8751040
71 + 8750969 = 8751040
83 + 8750957 = 8751040
107 + 8750933 = 8751040
149 + 8750891 = 8751040
167 + 8750873 = 8751040
173 + 8750867 = 8751040
197 + 8750843 = 8751040

Showing the first eight; more decompositions exist.
