Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105724, here are decompositions:

23 + 105701 = 105724
41 + 105683 = 105724
71 + 105653 = 105724
167 + 105557 = 105724
191 + 105533 = 105724
197 + 105527 = 105724
233 + 105491 = 105724
257 + 105467 = 105724

Showing the first eight; more decompositions exist.
