Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636920, here are decompositions:

3 + 8636917 = 8636920
11 + 8636909 = 8636920
101 + 8636819 = 8636920
179 + 8636741 = 8636920
293 + 8636627 = 8636920
317 + 8636603 = 8636920
659 + 8636261 = 8636920
683 + 8636237 = 8636920

Showing the first eight; more decompositions exist.
