Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691772, here are decompositions:

41 + 8691731 = 8691772
83 + 8691689 = 8691772
149 + 8691623 = 8691772
179 + 8691593 = 8691772
191 + 8691581 = 8691772
263 + 8691509 = 8691772
293 + 8691479 = 8691772
359 + 8691413 = 8691772

Showing the first eight; more decompositions exist.
