Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489438, here are decompositions:

7 + 489431 = 489438
11 + 489427 = 489438
29 + 489409 = 489438
31 + 489407 = 489438
71 + 489367 = 489438
101 + 489337 = 489438
109 + 489329 = 489438
139 + 489299 = 489438

Showing the first eight; more decompositions exist.
