Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691146, here are decompositions:

19 + 8691127 = 8691146
103 + 8691043 = 8691146
127 + 8691019 = 8691146
193 + 8690953 = 8691146
199 + 8690947 = 8691146
229 + 8690917 = 8691146
349 + 8690797 = 8691146
379 + 8690767 = 8691146

Showing the first eight; more decompositions exist.
