Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105384, here are decompositions:

5 + 105379 = 105384
11 + 105373 = 105384
17 + 105367 = 105384
23 + 105361 = 105384
43 + 105341 = 105384
47 + 105337 = 105384
53 + 105331 = 105384
61 + 105323 = 105384

Showing the first eight; more decompositions exist.
