Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105860, here are decompositions:

31 + 105829 = 105860
43 + 105817 = 105860
109 + 105751 = 105860
127 + 105733 = 105860
193 + 105667 = 105860
211 + 105649 = 105860
241 + 105619 = 105860
331 + 105529 = 105860

Showing the first eight; more decompositions exist.
