Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105194, here are decompositions:

97 + 105097 = 105194
157 + 105037 = 105194
163 + 105031 = 105194
223 + 104971 = 105194
241 + 104953 = 105194
277 + 104917 = 105194
283 + 104911 = 105194
367 + 104827 = 105194

Showing the first eight; more decompositions exist.
