Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105712, here are decompositions:

11 + 105701 = 105712
29 + 105683 = 105712
59 + 105653 = 105712
149 + 105563 = 105712
179 + 105533 = 105712
263 + 105449 = 105712
311 + 105401 = 105712
353 + 105359 = 105712

Showing the first eight; more decompositions exist.
