Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105814, here are decompositions:

47 + 105767 = 105814
53 + 105761 = 105814
113 + 105701 = 105814
131 + 105683 = 105814
251 + 105563 = 105814
257 + 105557 = 105814
281 + 105533 = 105814
311 + 105503 = 105814

Showing the first eight; more decompositions exist.
