Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490950, here are decompositions:

13 + 490937 = 490950
23 + 490927 = 490950
29 + 490921 = 490950
37 + 490913 = 490950
59 + 490891 = 490950
73 + 490877 = 490950
101 + 490849 = 490950
113 + 490837 = 490950

Showing the first eight; more decompositions exist.
