Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105146, here are decompositions:

3 + 105143 = 105146
109 + 105037 = 105146
127 + 105019 = 105146
193 + 104953 = 105146
199 + 104947 = 105146
229 + 104917 = 105146
277 + 104869 = 105146
367 + 104779 = 105146

Showing the first eight; more decompositions exist.
