Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20484, here are decompositions:

5 + 20479 = 20484
7 + 20477 = 20484
41 + 20443 = 20484
43 + 20441 = 20484
53 + 20431 = 20484
73 + 20411 = 20484
127 + 20357 = 20484
131 + 20353 = 20484

Showing the first eight; more decompositions exist.
