Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105758, here are decompositions:

7 + 105751 = 105758
31 + 105727 = 105758
67 + 105691 = 105758
109 + 105649 = 105758
139 + 105619 = 105758
151 + 105607 = 105758
157 + 105601 = 105758
229 + 105529 = 105758

Showing the first eight; more decompositions exist.
