Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751090, here are decompositions:

11 + 8751079 = 8751090
53 + 8751037 = 8751090
83 + 8751007 = 8751090
149 + 8750941 = 8751090
157 + 8750933 = 8751090
167 + 8750923 = 8751090
197 + 8750893 = 8751090
199 + 8750891 = 8751090

Showing the first eight; more decompositions exist.
