Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105266, here are decompositions:

3 + 105263 = 105266
13 + 105253 = 105266
37 + 105229 = 105266
67 + 105199 = 105266
229 + 105037 = 105266
307 + 104959 = 105266
313 + 104953 = 105266
349 + 104917 = 105266

Showing the first eight; more decompositions exist.
