Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490066, here are decompositions:

47 + 490019 = 490066
89 + 489977 = 490066
107 + 489959 = 490066
179 + 489887 = 490066
197 + 489869 = 490066
233 + 489833 = 490066
263 + 489803 = 490066
389 + 489677 = 490066

Showing the first eight; more decompositions exist.
