Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490944, here are decompositions:

7 + 490937 = 490944
17 + 490927 = 490944
23 + 490921 = 490944
31 + 490913 = 490944
53 + 490891 = 490944
67 + 490877 = 490944
107 + 490837 = 490944
173 + 490771 = 490944

Showing the first eight; more decompositions exist.
