Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154194, here are decompositions:

11 + 154183 = 154194
13 + 154181 = 154194
37 + 154157 = 154194
41 + 154153 = 154194
67 + 154127 = 154194
83 + 154111 = 154194
97 + 154097 = 154194
107 + 154087 = 154194

Showing the first eight; more decompositions exist.
