Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105726, here are decompositions:

43 + 105683 = 105726
53 + 105673 = 105726
59 + 105667 = 105726
73 + 105653 = 105726
107 + 105619 = 105726
113 + 105613 = 105726
163 + 105563 = 105726
193 + 105533 = 105726

Showing the first eight; more decompositions exist.
