Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691806, here are decompositions:

3 + 8691803 = 8691806
7 + 8691799 = 8691806
43 + 8691763 = 8691806
73 + 8691733 = 8691806
139 + 8691667 = 8691806
163 + 8691643 = 8691806
223 + 8691583 = 8691806
337 + 8691469 = 8691806

Showing the first eight; more decompositions exist.
