Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105976, here are decompositions:

5 + 105971 = 105976
23 + 105953 = 105976
47 + 105929 = 105976
113 + 105863 = 105976
293 + 105683 = 105976
419 + 105557 = 105976
443 + 105533 = 105976
449 + 105527 = 105976

Showing the first eight; more decompositions exist.
