Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 494918, here are decompositions:

19 + 494899 = 494918
157 + 494761 = 494918
181 + 494737 = 494918
199 + 494719 = 494918
241 + 494677 = 494918
271 + 494647 = 494918
331 + 494587 = 494918
379 + 494539 = 494918

Showing the first eight; more decompositions exist.
