Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105746, here are decompositions:

13 + 105733 = 105746
19 + 105727 = 105746
73 + 105673 = 105746
79 + 105667 = 105746
97 + 105649 = 105746
127 + 105619 = 105746
139 + 105607 = 105746
229 + 105517 = 105746

Showing the first eight; more decompositions exist.
