Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691430, here are decompositions:

17 + 8691413 = 8691430
23 + 8691407 = 8691430
47 + 8691383 = 8691430
71 + 8691359 = 8691430
131 + 8691299 = 8691430
149 + 8691281 = 8691430
179 + 8691251 = 8691430
191 + 8691239 = 8691430

Showing the first eight; more decompositions exist.
