Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691422, here are decompositions:

31 + 8691391 = 8691422
109 + 8691313 = 8691422
193 + 8691229 = 8691422
199 + 8691223 = 8691422
211 + 8691211 = 8691422
331 + 8691091 = 8691422
379 + 8691043 = 8691422
463 + 8690959 = 8691422

Showing the first eight; more decompositions exist.
