Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490042, here are decompositions:

11 + 490031 = 490042
23 + 490019 = 490042
41 + 490001 = 490042
53 + 489989 = 490042
83 + 489959 = 490042
101 + 489941 = 490042
131 + 489911 = 490042
173 + 489869 = 490042

Showing the first eight; more decompositions exist.
