Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746420, here are decompositions:

29 + 8746391 = 8746420
41 + 8746379 = 8746420
149 + 8746271 = 8746420
191 + 8746229 = 8746420
197 + 8746223 = 8746420
227 + 8746193 = 8746420
383 + 8746037 = 8746420
491 + 8745929 = 8746420

Showing the first eight; more decompositions exist.
