Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636978, here are decompositions:

19 + 8636959 = 8636978
61 + 8636917 = 8636978
67 + 8636911 = 8636978
79 + 8636899 = 8636978
109 + 8636869 = 8636978
139 + 8636839 = 8636978
199 + 8636779 = 8636978
241 + 8636737 = 8636978

Showing the first eight; more decompositions exist.
