Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105842, here are decompositions:

13 + 105829 = 105842
73 + 105769 = 105842
109 + 105733 = 105842
151 + 105691 = 105842
193 + 105649 = 105842
223 + 105619 = 105842
229 + 105613 = 105842
241 + 105601 = 105842

Showing the first eight; more decompositions exist.
