Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691688, here are decompositions:

101 + 8691587 = 8691688
107 + 8691581 = 8691688
179 + 8691509 = 8691688
191 + 8691497 = 8691688
281 + 8691407 = 8691688
389 + 8691299 = 8691688
419 + 8691269 = 8691688
449 + 8691239 = 8691688

Showing the first eight; more decompositions exist.
