Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105750, here are decompositions:

17 + 105733 = 105750
23 + 105727 = 105750
59 + 105691 = 105750
67 + 105683 = 105750
83 + 105667 = 105750
97 + 105653 = 105750
101 + 105649 = 105750
131 + 105619 = 105750

Showing the first eight; more decompositions exist.
