Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489146, here are decompositions:

13 + 489133 = 489146
19 + 489127 = 489146
37 + 489109 = 489146
103 + 489043 = 489146
127 + 489019 = 489146
199 + 488947 = 489146
313 + 488833 = 489146
349 + 488797 = 489146

Showing the first eight; more decompositions exist.
