Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105722, here are decompositions:

31 + 105691 = 105722
73 + 105649 = 105722
103 + 105619 = 105722
109 + 105613 = 105722
181 + 105541 = 105722
193 + 105529 = 105722
223 + 105499 = 105722
349 + 105373 = 105722

Showing the first eight; more decompositions exist.
