Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8636198, here are decompositions:

31 + 8636167 = 8636198
61 + 8636137 = 8636198
199 + 8635999 = 8636198
229 + 8635969 = 8636198
271 + 8635927 = 8636198
331 + 8635867 = 8636198
349 + 8635849 = 8636198
421 + 8635777 = 8636198

Showing the first eight; more decompositions exist.
