Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157194, here are decompositions:

5 + 157189 = 157194
13 + 157181 = 157194
17 + 157177 = 157194
31 + 157163 = 157194
53 + 157141 = 157194
61 + 157133 = 157194
67 + 157127 = 157194
113 + 157081 = 157194

Showing the first eight; more decompositions exist.
