Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489774, here are decompositions:

13 + 489761 = 489774
31 + 489743 = 489774
41 + 489733 = 489774
83 + 489691 = 489774
97 + 489677 = 489774
101 + 489673 = 489774
223 + 489551 = 489774
281 + 489493 = 489774

Showing the first eight; more decompositions exist.
