Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719266, here are decompositions:

5 + 8719261 = 8719266
13 + 8719253 = 8719266
43 + 8719223 = 8719266
47 + 8719219 = 8719266
53 + 8719213 = 8719266
67 + 8719199 = 8719266
79 + 8719187 = 8719266
89 + 8719177 = 8719266

Showing the first eight; more decompositions exist.
