Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489538, here are decompositions:

59 + 489479 = 489538
89 + 489449 = 489538
107 + 489431 = 489538
131 + 489407 = 489538
149 + 489389 = 489538
239 + 489299 = 489538
281 + 489257 = 489538
347 + 489191 = 489538

Showing the first eight; more decompositions exist.
