Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749938, here are decompositions:

11 + 8749927 = 8749938
17 + 8749921 = 8749938
47 + 8749891 = 8749938
97 + 8749841 = 8749938
101 + 8749837 = 8749938
149 + 8749789 = 8749938
151 + 8749787 = 8749938
167 + 8749771 = 8749938

Showing the first eight; more decompositions exist.
