Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672938, here are decompositions:

5 + 8672933 = 8672938
11 + 8672927 = 8672938
41 + 8672897 = 8672938
47 + 8672891 = 8672938
107 + 8672831 = 8672938
137 + 8672801 = 8672938
149 + 8672789 = 8672938
251 + 8672687 = 8672938

Showing the first eight; more decompositions exist.
