Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719164, here are decompositions:

5 + 8719159 = 8719164
23 + 8719141 = 8719164
31 + 8719133 = 8719164
37 + 8719127 = 8719164
107 + 8719057 = 8719164
127 + 8719037 = 8719164
191 + 8718973 = 8719164
211 + 8718953 = 8719164

Showing the first eight; more decompositions exist.
