Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105940, here are decompositions:

11 + 105929 = 105940
41 + 105899 = 105940
173 + 105767 = 105940
179 + 105761 = 105940
239 + 105701 = 105940
257 + 105683 = 105940
383 + 105557 = 105940
431 + 105509 = 105940

Showing the first eight; more decompositions exist.
