Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489818, here are decompositions:

19 + 489799 = 489818
127 + 489691 = 489818
139 + 489679 = 489818
331 + 489487 = 489818
379 + 489439 = 489818
409 + 489409 = 489818
457 + 489361 = 489818
577 + 489241 = 489818

Showing the first eight; more decompositions exist.
