Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105790, here are decompositions:

23 + 105767 = 105790
29 + 105761 = 105790
89 + 105701 = 105790
107 + 105683 = 105790
137 + 105653 = 105790
227 + 105563 = 105790
233 + 105557 = 105790
257 + 105533 = 105790

Showing the first eight; more decompositions exist.
