Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751122, here are decompositions:

31 + 8751091 = 8751122
43 + 8751079 = 8751122
109 + 8751013 = 8751122
181 + 8750941 = 8751122
199 + 8750923 = 8751122
229 + 8750893 = 8751122
241 + 8750881 = 8751122
313 + 8750809 = 8751122

Showing the first eight; more decompositions exist.
