Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105156, here are decompositions:

13 + 105143 = 105156
19 + 105137 = 105156
59 + 105097 = 105156
137 + 105019 = 105156
157 + 104999 = 105156
197 + 104959 = 105156
223 + 104933 = 105156
239 + 104917 = 105156

Showing the first eight; more decompositions exist.
