Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105766, here are decompositions:

5 + 105761 = 105766
83 + 105683 = 105766
113 + 105653 = 105766
233 + 105533 = 105766
239 + 105527 = 105766
257 + 105509 = 105766
263 + 105503 = 105766
317 + 105449 = 105766

Showing the first eight; more decompositions exist.
