Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751778, here are decompositions:

5 + 8751773 = 8751778
11 + 8751767 = 8751778
29 + 8751749 = 8751778
107 + 8751671 = 8751778
149 + 8751629 = 8751778
179 + 8751599 = 8751778
251 + 8751527 = 8751778
311 + 8751467 = 8751778

Showing the first eight; more decompositions exist.
