Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691986, here are decompositions:

7 + 8691979 = 8691986
13 + 8691973 = 8691986
97 + 8691889 = 8691986
103 + 8691883 = 8691986
223 + 8691763 = 8691986
313 + 8691673 = 8691986
397 + 8691589 = 8691986
613 + 8691373 = 8691986

Showing the first eight; more decompositions exist.
