Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684040, here are decompositions:

11 + 8684029 = 8684040
17 + 8684023 = 8684040
31 + 8684009 = 8684040
37 + 8684003 = 8684040
97 + 8683943 = 8684040
107 + 8683933 = 8684040
163 + 8683877 = 8684040
257 + 8683783 = 8684040

Showing the first eight; more decompositions exist.
