Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105426, here are decompositions:

19 + 105407 = 105426
29 + 105397 = 105426
37 + 105389 = 105426
47 + 105379 = 105426
53 + 105373 = 105426
59 + 105367 = 105426
67 + 105359 = 105426
89 + 105337 = 105426

Showing the first eight; more decompositions exist.
