Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751826, here are decompositions:

23 + 8751803 = 8751826
53 + 8751773 = 8751826
59 + 8751767 = 8751826
197 + 8751629 = 8751826
227 + 8751599 = 8751826
233 + 8751593 = 8751826
263 + 8751563 = 8751826
269 + 8751557 = 8751826

Showing the first eight; more decompositions exist.
