Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621406, here are decompositions:

29 + 8621377 = 8621406
67 + 8621339 = 8621406
97 + 8621309 = 8621406
107 + 8621299 = 8621406
163 + 8621243 = 8621406
193 + 8621213 = 8621406
197 + 8621209 = 8621406
223 + 8621183 = 8621406

Showing the first eight; more decompositions exist.
