Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105944, here are decompositions:

31 + 105913 = 105944
37 + 105907 = 105944
61 + 105883 = 105944
73 + 105871 = 105944
127 + 105817 = 105944
193 + 105751 = 105944
211 + 105733 = 105944
271 + 105673 = 105944

Showing the first eight; more decompositions exist.
