Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23040, here are decompositions:

11 + 23029 = 23040
13 + 23027 = 23040
19 + 23021 = 23040
23 + 23017 = 23040
29 + 23011 = 23040
37 + 23003 = 23040
47 + 22993 = 23040
67 + 22973 = 23040

Showing the first eight; more decompositions exist.
