Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20040, here are decompositions:

11 + 20029 = 20040
17 + 20023 = 20040
19 + 20021 = 20040
29 + 20011 = 20040
43 + 19997 = 20040
47 + 19993 = 20040
61 + 19979 = 20040
67 + 19973 = 20040

Showing the first eight; more decompositions exist.
