Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105826, here are decompositions:

59 + 105767 = 105826
173 + 105653 = 105826
263 + 105563 = 105826
269 + 105557 = 105826
293 + 105533 = 105826
317 + 105509 = 105826
359 + 105467 = 105826
389 + 105437 = 105826

Showing the first eight; more decompositions exist.
