Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691948, here are decompositions:

7 + 8691941 = 8691948
11 + 8691937 = 8691948
47 + 8691901 = 8691948
59 + 8691889 = 8691948
149 + 8691799 = 8691948
197 + 8691751 = 8691948
281 + 8691667 = 8691948
359 + 8691589 = 8691948

Showing the first eight; more decompositions exist.
