Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105188, here are decompositions:

151 + 105037 = 105188
157 + 105031 = 105188
229 + 104959 = 105188
241 + 104947 = 105188
271 + 104917 = 105188
277 + 104911 = 105188
337 + 104851 = 105188
409 + 104779 = 105188

Showing the first eight; more decompositions exist.
