Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691412, here are decompositions:

5 + 8691407 = 8691412
29 + 8691383 = 8691412
53 + 8691359 = 8691412
113 + 8691299 = 8691412
131 + 8691281 = 8691412
173 + 8691239 = 8691412
293 + 8691119 = 8691412
311 + 8691101 = 8691412

Showing the first eight; more decompositions exist.
