Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 81194, here are decompositions:

13 + 81181 = 81194
31 + 81163 = 81194
37 + 81157 = 81194
97 + 81097 = 81194
151 + 81043 = 81194
163 + 81031 = 81194
181 + 81013 = 81194
193 + 81001 = 81194

Showing the first eight; more decompositions exist.
