Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105408, here are decompositions:

7 + 105401 = 105408
11 + 105397 = 105408
19 + 105389 = 105408
29 + 105379 = 105408
41 + 105367 = 105408
47 + 105361 = 105408
67 + 105341 = 105408
71 + 105337 = 105408

Showing the first eight; more decompositions exist.
