Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691718, here are decompositions:

29 + 8691689 = 8691718
131 + 8691587 = 8691718
137 + 8691581 = 8691718
239 + 8691479 = 8691718
311 + 8691407 = 8691718
359 + 8691359 = 8691718
419 + 8691299 = 8691718
449 + 8691269 = 8691718

Showing the first eight; more decompositions exist.
