Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751198, here are decompositions:

17 + 8751181 = 8751198
41 + 8751157 = 8751198
47 + 8751151 = 8751198
59 + 8751139 = 8751198
97 + 8751101 = 8751198
101 + 8751097 = 8751198
107 + 8751091 = 8751198
109 + 8751089 = 8751198

Showing the first eight; more decompositions exist.
