Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 41920, here are decompositions:

17 + 41903 = 41920
23 + 41897 = 41920
41 + 41879 = 41920
71 + 41849 = 41920
107 + 41813 = 41920
149 + 41771 = 41920
191 + 41729 = 41920
233 + 41687 = 41920

Showing the first eight; more decompositions exist.
