Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489992, here are decompositions:

3 + 489989 = 489992
31 + 489961 = 489992
79 + 489913 = 489992
193 + 489799 = 489992
199 + 489793 = 489992
313 + 489679 = 489992
379 + 489613 = 489992
421 + 489571 = 489992

Showing the first eight; more decompositions exist.
