Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691616, here are decompositions:

23 + 8691593 = 8691616
29 + 8691587 = 8691616
107 + 8691509 = 8691616
137 + 8691479 = 8691616
233 + 8691383 = 8691616
257 + 8691359 = 8691616
317 + 8691299 = 8691616
347 + 8691269 = 8691616

Showing the first eight; more decompositions exist.
