Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8631194, here are decompositions:

3 + 8631191 = 8631194
43 + 8631151 = 8631194
97 + 8631097 = 8631194
157 + 8631037 = 8631194
193 + 8631001 = 8631194
211 + 8630983 = 8631194
223 + 8630971 = 8631194
337 + 8630857 = 8631194

Showing the first eight; more decompositions exist.
