Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684940, here are decompositions:

29 + 8684911 = 8684940
37 + 8684903 = 8684940
67 + 8684873 = 8684940
79 + 8684861 = 8684940
109 + 8684831 = 8684940
151 + 8684789 = 8684940
157 + 8684783 = 8684940
179 + 8684761 = 8684940

Showing the first eight; more decompositions exist.
