Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746638, here are decompositions:

29 + 8746609 = 8746638
179 + 8746459 = 8746638
191 + 8746447 = 8746638
211 + 8746427 = 8746638
239 + 8746399 = 8746638
269 + 8746369 = 8746638
281 + 8746357 = 8746638
337 + 8746301 = 8746638

Showing the first eight; more decompositions exist.
