Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691472, here are decompositions:

3 + 8691469 = 8691472
59 + 8691413 = 8691472
89 + 8691383 = 8691472
113 + 8691359 = 8691472
173 + 8691299 = 8691472
191 + 8691281 = 8691472
233 + 8691239 = 8691472
263 + 8691209 = 8691472

Showing the first eight; more decompositions exist.
