Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105152, here are decompositions:

181 + 104971 = 105152
193 + 104959 = 105152
199 + 104953 = 105152
241 + 104911 = 105152
283 + 104869 = 105152
349 + 104803 = 105152
373 + 104779 = 105152
379 + 104773 = 105152

Showing the first eight; more decompositions exist.
