Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691194, here are decompositions:

7 + 8691187 = 8691194
37 + 8691157 = 8691194
67 + 8691127 = 8691194
103 + 8691091 = 8691194
151 + 8691043 = 8691194
223 + 8690971 = 8691194
241 + 8690953 = 8691194
277 + 8690917 = 8691194

Showing the first eight; more decompositions exist.
