Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105770, here are decompositions:

3 + 105767 = 105770
19 + 105751 = 105770
37 + 105733 = 105770
43 + 105727 = 105770
79 + 105691 = 105770
97 + 105673 = 105770
103 + 105667 = 105770
151 + 105619 = 105770

Showing the first eight; more decompositions exist.
