Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489752, here are decompositions:

19 + 489733 = 489752
61 + 489691 = 489752
73 + 489679 = 489752
79 + 489673 = 489752
139 + 489613 = 489752
181 + 489571 = 489752
199 + 489553 = 489752
223 + 489529 = 489752

Showing the first eight; more decompositions exist.
