Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105738, here are decompositions:

5 + 105733 = 105738
11 + 105727 = 105738
37 + 105701 = 105738
47 + 105691 = 105738
71 + 105667 = 105738
89 + 105649 = 105738
131 + 105607 = 105738
137 + 105601 = 105738

Showing the first eight; more decompositions exist.
