Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105668, here are decompositions:

19 + 105649 = 105668
61 + 105607 = 105668
67 + 105601 = 105668
127 + 105541 = 105668
139 + 105529 = 105668
151 + 105517 = 105668
271 + 105397 = 105668
307 + 105361 = 105668

Showing the first eight; more decompositions exist.
