Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719138, here are decompositions:

5 + 8719133 = 8719138
11 + 8719127 = 8719138
89 + 8719049 = 8719138
101 + 8719037 = 8719138
107 + 8719031 = 8719138
251 + 8718887 = 8719138
257 + 8718881 = 8719138
269 + 8718869 = 8719138

Showing the first eight; more decompositions exist.
