Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691724, here are decompositions:

71 + 8691653 = 8691724
101 + 8691623 = 8691724
131 + 8691593 = 8691724
137 + 8691587 = 8691724
227 + 8691497 = 8691724
311 + 8691413 = 8691724
317 + 8691407 = 8691724
443 + 8691281 = 8691724

Showing the first eight; more decompositions exist.
