Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691266, here are decompositions:

19 + 8691247 = 8691266
37 + 8691229 = 8691266
43 + 8691223 = 8691266
79 + 8691187 = 8691266
109 + 8691157 = 8691266
139 + 8691127 = 8691266
223 + 8691043 = 8691266
307 + 8690959 = 8691266

Showing the first eight; more decompositions exist.
