Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 489892, here are decompositions:

5 + 489887 = 489892
23 + 489869 = 489892
41 + 489851 = 489892
59 + 489833 = 489892
89 + 489803 = 489892
101 + 489791 = 489892
131 + 489761 = 489892
149 + 489743 = 489892

Showing the first eight; more decompositions exist.
