Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40958, here are decompositions:

19 + 40939 = 40958
31 + 40927 = 40958
61 + 40897 = 40958
79 + 40879 = 40958
109 + 40849 = 40958
139 + 40819 = 40958
157 + 40801 = 40958
199 + 40759 = 40958

Showing the first eight; more decompositions exist.
