Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105844, here are decompositions:

83 + 105761 = 105844
191 + 105653 = 105844
281 + 105563 = 105844
311 + 105533 = 105844
317 + 105527 = 105844
353 + 105491 = 105844
443 + 105401 = 105844
503 + 105341 = 105844

Showing the first eight; more decompositions exist.
