Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105886, here are decompositions:

3 + 105883 = 105886
23 + 105863 = 105886
233 + 105653 = 105886
353 + 105533 = 105886
359 + 105527 = 105886
383 + 105503 = 105886
419 + 105467 = 105886
449 + 105437 = 105886

Showing the first eight; more decompositions exist.
