Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105956, here are decompositions:

3 + 105953 = 105956
13 + 105943 = 105956
43 + 105913 = 105956
73 + 105883 = 105956
127 + 105829 = 105956
139 + 105817 = 105956
223 + 105733 = 105956
229 + 105727 = 105956

Showing the first eight; more decompositions exist.
