Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691222, here are decompositions:

11 + 8691211 = 8691222
13 + 8691209 = 8691222
103 + 8691119 = 8691222
131 + 8691091 = 8691222
179 + 8691043 = 8691222
251 + 8690971 = 8691222
263 + 8690959 = 8691222
269 + 8690953 = 8691222

Showing the first eight; more decompositions exist.
