Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10194, here are decompositions:

13 + 10181 = 10194
17 + 10177 = 10194
31 + 10163 = 10194
43 + 10151 = 10194
53 + 10141 = 10194
61 + 10133 = 10194
83 + 10111 = 10194
101 + 10093 = 10194

Showing the first eight; more decompositions exist.
