Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494868, here are decompositions:

19 + 494849 = 494868
79 + 494789 = 494868
107 + 494761 = 494868
109 + 494759 = 494868
131 + 494737 = 494868
137 + 494731 = 494868
149 + 494719 = 494868
181 + 494687 = 494868

Showing the first eight; more decompositions exist.
