Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105670, here are decompositions:

3 + 105667 = 105670
17 + 105653 = 105670
107 + 105563 = 105670
113 + 105557 = 105670
137 + 105533 = 105670
167 + 105503 = 105670
179 + 105491 = 105670
233 + 105437 = 105670

Showing the first eight; more decompositions exist.
