Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637194, here are decompositions:

31 + 8637163 = 8637194
43 + 8637151 = 8637194
61 + 8637133 = 8637194
103 + 8637091 = 8637194
127 + 8637067 = 8637194
271 + 8636923 = 8637194
277 + 8636917 = 8637194
283 + 8636911 = 8637194

Showing the first eight; more decompositions exist.
