Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 45840, here are decompositions:

7 + 45833 = 45840
13 + 45827 = 45840
17 + 45823 = 45840
19 + 45821 = 45840
23 + 45817 = 45840
61 + 45779 = 45840
73 + 45767 = 45840
83 + 45757 = 45840

Showing the first eight; more decompositions exist.
