Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636940, here are decompositions:

17 + 8636923 = 8636940
19 + 8636921 = 8636940
23 + 8636917 = 8636940
29 + 8636911 = 8636940
31 + 8636909 = 8636940
41 + 8636899 = 8636940
47 + 8636893 = 8636940
71 + 8636869 = 8636940

Showing the first eight; more decompositions exist.
