Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691396, here are decompositions:

5 + 8691391 = 8691396
13 + 8691383 = 8691396
23 + 8691373 = 8691396
29 + 8691367 = 8691396
37 + 8691359 = 8691396
83 + 8691313 = 8691396
97 + 8691299 = 8691396
127 + 8691269 = 8691396

Showing the first eight; more decompositions exist.
