Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490580, here are decompositions:

3 + 490577 = 490580
7 + 490573 = 490580
31 + 490549 = 490580
37 + 490543 = 490580
43 + 490537 = 490580
61 + 490519 = 490580
127 + 490453 = 490580
163 + 490417 = 490580

Showing the first eight; more decompositions exist.
