Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105162, here are decompositions:

19 + 105143 = 105162
131 + 105031 = 105162
139 + 105023 = 105162
163 + 104999 = 105162
191 + 104971 = 105162
229 + 104933 = 105162
251 + 104911 = 105162
271 + 104891 = 105162

Showing the first eight; more decompositions exist.
