Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719198, here are decompositions:

11 + 8719187 = 8719198
71 + 8719127 = 8719198
149 + 8719049 = 8719198
167 + 8719031 = 8719198
281 + 8718917 = 8719198
311 + 8718887 = 8719198
317 + 8718881 = 8719198
347 + 8718851 = 8719198

Showing the first eight; more decompositions exist.
