Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105926, here are decompositions:

13 + 105913 = 105926
19 + 105907 = 105926
43 + 105883 = 105926
97 + 105829 = 105926
109 + 105817 = 105926
157 + 105769 = 105926
193 + 105733 = 105926
199 + 105727 = 105926

Showing the first eight; more decompositions exist.
