Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105892, here are decompositions:

29 + 105863 = 105892
131 + 105761 = 105892
191 + 105701 = 105892
239 + 105653 = 105892
359 + 105533 = 105892
383 + 105509 = 105892
389 + 105503 = 105892
401 + 105491 = 105892

Showing the first eight; more decompositions exist.
