Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40858, here are decompositions:

5 + 40853 = 40858
11 + 40847 = 40858
17 + 40841 = 40858
29 + 40829 = 40858
71 + 40787 = 40858
107 + 40751 = 40858
149 + 40709 = 40858
281 + 40577 = 40858

Showing the first eight; more decompositions exist.
