Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105744, here are decompositions:

11 + 105733 = 105744
17 + 105727 = 105744
43 + 105701 = 105744
53 + 105691 = 105744
61 + 105683 = 105744
71 + 105673 = 105744
131 + 105613 = 105744
137 + 105607 = 105744

Showing the first eight; more decompositions exist.
