Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719340, here are decompositions:

13 + 8719327 = 8719340
37 + 8719303 = 8719340
67 + 8719273 = 8719340
79 + 8719261 = 8719340
127 + 8719213 = 8719340
163 + 8719177 = 8719340
181 + 8719159 = 8719340
199 + 8719141 = 8719340

Showing the first eight; more decompositions exist.
