Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490244, here are decompositions:

3 + 490241 = 490244
37 + 490207 = 490244
43 + 490201 = 490244
61 + 490183 = 490244
127 + 490117 = 490244
211 + 490033 = 490244
241 + 490003 = 490244
283 + 489961 = 490244

Showing the first eight; more decompositions exist.
