Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691658, here are decompositions:

5 + 8691653 = 8691658
71 + 8691587 = 8691658
149 + 8691509 = 8691658
179 + 8691479 = 8691658
251 + 8691407 = 8691658
359 + 8691299 = 8691658
389 + 8691269 = 8691658
419 + 8691239 = 8691658

Showing the first eight; more decompositions exist.
