Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105782, here are decompositions:

13 + 105769 = 105782
31 + 105751 = 105782
109 + 105673 = 105782
163 + 105619 = 105782
181 + 105601 = 105782
241 + 105541 = 105782
283 + 105499 = 105782
409 + 105373 = 105782

Showing the first eight; more decompositions exist.
