Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751142, here are decompositions:

3 + 8751139 = 8751142
41 + 8751101 = 8751142
53 + 8751089 = 8751142
173 + 8750969 = 8751142
251 + 8750891 = 8751142
269 + 8750873 = 8751142
311 + 8750831 = 8751142
359 + 8750783 = 8751142

Showing the first eight; more decompositions exist.
