Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684788, here are decompositions:

5 + 8684783 = 8684788
17 + 8684771 = 8684788
29 + 8684759 = 8684788
41 + 8684747 = 8684788
89 + 8684699 = 8684788
131 + 8684657 = 8684788
191 + 8684597 = 8684788
251 + 8684537 = 8684788

Showing the first eight; more decompositions exist.
