Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105356, here are decompositions:

19 + 105337 = 105356
37 + 105319 = 105356
79 + 105277 = 105356
103 + 105253 = 105356
127 + 105229 = 105356
157 + 105199 = 105356
337 + 105019 = 105356
397 + 104959 = 105356

Showing the first eight; more decompositions exist.
