Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105718, here are decompositions:

17 + 105701 = 105718
191 + 105527 = 105718
227 + 105491 = 105718
251 + 105467 = 105718
269 + 105449 = 105718
281 + 105437 = 105718
311 + 105407 = 105718
317 + 105401 = 105718

Showing the first eight; more decompositions exist.
