Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105748, here are decompositions:

47 + 105701 = 105748
191 + 105557 = 105748
239 + 105509 = 105748
257 + 105491 = 105748
281 + 105467 = 105748
311 + 105437 = 105748
347 + 105401 = 105748
359 + 105389 = 105748

Showing the first eight; more decompositions exist.
