Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 488020, here are decompositions:

11 + 488009 = 488020
17 + 488003 = 488020
23 + 487997 = 488020
41 + 487979 = 488020
47 + 487973 = 488020
131 + 487889 = 488020
191 + 487829 = 488020
227 + 487793 = 488020

Showing the first eight; more decompositions exist.
