Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105788, here are decompositions:

19 + 105769 = 105788
37 + 105751 = 105788
61 + 105727 = 105788
97 + 105691 = 105788
139 + 105649 = 105788
181 + 105607 = 105788
271 + 105517 = 105788
409 + 105379 = 105788

Showing the first eight; more decompositions exist.
