Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751772, here are decompositions:

5 + 8751767 = 8751772
23 + 8751749 = 8751772
101 + 8751671 = 8751772
173 + 8751599 = 8751772
179 + 8751593 = 8751772
269 + 8751503 = 8751772
311 + 8751461 = 8751772
401 + 8751371 = 8751772

Showing the first eight; more decompositions exist.
