Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751186, here are decompositions:

5 + 8751181 = 8751186
13 + 8751173 = 8751186
29 + 8751157 = 8751186
43 + 8751143 = 8751186
47 + 8751139 = 8751186
89 + 8751097 = 8751186
97 + 8751089 = 8751186
107 + 8751079 = 8751186

Showing the first eight; more decompositions exist.
