Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489380, here are decompositions:

13 + 489367 = 489380
19 + 489361 = 489380
37 + 489343 = 489380
43 + 489337 = 489380
97 + 489283 = 489380
139 + 489241 = 489380
163 + 489217 = 489380
223 + 489157 = 489380

Showing the first eight; more decompositions exist.
