Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105706, here are decompositions:

5 + 105701 = 105706
23 + 105683 = 105706
53 + 105653 = 105706
149 + 105557 = 105706
173 + 105533 = 105706
179 + 105527 = 105706
197 + 105509 = 105706
239 + 105467 = 105706

Showing the first eight; more decompositions exist.
