Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494890, here are decompositions:

17 + 494873 = 494890
41 + 494849 = 494890
47 + 494843 = 494890
101 + 494789 = 494890
107 + 494783 = 494890
131 + 494759 = 494890
167 + 494723 = 494890
191 + 494699 = 494890

Showing the first eight; more decompositions exist.
