Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691406, here are decompositions:

23 + 8691383 = 8691406
47 + 8691359 = 8691406
107 + 8691299 = 8691406
137 + 8691269 = 8691406
167 + 8691239 = 8691406
197 + 8691209 = 8691406
239 + 8691167 = 8691406
443 + 8690963 = 8691406

Showing the first eight; more decompositions exist.
