Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684980, here are decompositions:

41 + 8684939 = 8684980
107 + 8684873 = 8684980
149 + 8684831 = 8684980
191 + 8684789 = 8684980
197 + 8684783 = 8684980
233 + 8684747 = 8684980
281 + 8684699 = 8684980
383 + 8684597 = 8684980

Showing the first eight; more decompositions exist.
