Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489020, here are decompositions:

19 + 489001 = 489020
61 + 488959 = 489020
73 + 488947 = 489020
127 + 488893 = 489020
193 + 488827 = 489020
199 + 488821 = 489020
223 + 488797 = 489020
229 + 488791 = 489020

Showing the first eight; more decompositions exist.
