Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691066, here are decompositions:

23 + 8691043 = 8691066
47 + 8691019 = 8691066
103 + 8690963 = 8691066
107 + 8690959 = 8691066
113 + 8690953 = 8691066
149 + 8690917 = 8691066
199 + 8690867 = 8691066
239 + 8690827 = 8691066

Showing the first eight; more decompositions exist.
