Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691900, here are decompositions:

11 + 8691889 = 8691900
17 + 8691883 = 8691900
47 + 8691853 = 8691900
67 + 8691833 = 8691900
73 + 8691827 = 8691900
97 + 8691803 = 8691900
101 + 8691799 = 8691900
137 + 8691763 = 8691900

Showing the first eight; more decompositions exist.
