Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490102, here are decompositions:

5 + 490097 = 490102
71 + 490031 = 490102
83 + 490019 = 490102
101 + 490001 = 490102
113 + 489989 = 490102
191 + 489911 = 490102
233 + 489869 = 490102
251 + 489851 = 490102

Showing the first eight; more decompositions exist.
