Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8684964, here are decompositions:

5 + 8684959 = 8684964
17 + 8684947 = 8684964
23 + 8684941 = 8684964
53 + 8684911 = 8684964
61 + 8684903 = 8684964
103 + 8684861 = 8684964
181 + 8684783 = 8684964
193 + 8684771 = 8684964

Showing the first eight; more decompositions exist.
