Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490994, here are decompositions:

3 + 490991 = 490994
37 + 490957 = 490994
43 + 490951 = 490994
67 + 490927 = 490994
73 + 490921 = 490994
103 + 490891 = 490994
157 + 490837 = 490994
211 + 490783 = 490994

Showing the first eight; more decompositions exist.
