Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691418, here are decompositions:

5 + 8691413 = 8691418
11 + 8691407 = 8691418
59 + 8691359 = 8691418
137 + 8691281 = 8691418
149 + 8691269 = 8691418
167 + 8691251 = 8691418
179 + 8691239 = 8691418
251 + 8691167 = 8691418

Showing the first eight; more decompositions exist.
