Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691358, here are decompositions:

59 + 8691299 = 8691358
89 + 8691269 = 8691358
107 + 8691251 = 8691358
149 + 8691209 = 8691358
191 + 8691167 = 8691358
239 + 8691119 = 8691358
257 + 8691101 = 8691358
491 + 8690867 = 8691358

Showing the first eight; more decompositions exist.
