Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489780, here are decompositions:

19 + 489761 = 489780
37 + 489743 = 489780
47 + 489733 = 489780
89 + 489691 = 489780
101 + 489679 = 489780
103 + 489677 = 489780
107 + 489673 = 489780
127 + 489653 = 489780

Showing the first eight; more decompositions exist.
