Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684890, here are decompositions:

17 + 8684873 = 8684890
29 + 8684861 = 8684890
59 + 8684831 = 8684890
101 + 8684789 = 8684890
107 + 8684783 = 8684890
131 + 8684759 = 8684890
191 + 8684699 = 8684890
197 + 8684693 = 8684890

Showing the first eight; more decompositions exist.
