Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8751080, here are decompositions:

43 + 8751037 = 8751080
67 + 8751013 = 8751080
73 + 8751007 = 8751080
139 + 8750941 = 8751080
157 + 8750923 = 8751080
199 + 8750881 = 8751080
223 + 8750857 = 8751080
271 + 8750809 = 8751080

Showing the first eight; more decompositions exist.
