Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105546, here are decompositions:

5 + 105541 = 105546
13 + 105533 = 105546
17 + 105529 = 105546
19 + 105527 = 105546
29 + 105517 = 105546
37 + 105509 = 105546
43 + 105503 = 105546
47 + 105499 = 105546

Showing the first eight; more decompositions exist.
